* slab allocators: Remove SLAB_DEBUG_INITIAL flagChristoph Lameter2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.

* mm: make read_cache_page synchronousNick Piggin2007-05-07
| | | | | | | | | | | | | | | | Ensure pages are uptodate after returning from read_cache_page, which allows us to cut out most of the filesystem-internal PageUptodate calls. I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | OCFS2_I(inode)->ip_alloc_sem is a read-write semaphore protecting local concurrent access of ocfs2 inodes. However, ocfs2 directories were not taking the semaphore while they accessed or modified the allocation tree. ocfs2_extend_dir() needs to take the semaphore in a write mode when it adds to the allocation. All other directory users get there via ocfs2_bread(), which takes the semaphore in read mode. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

* ocfs2: Cache extent recordsMark Fasheh2007-04-26
| | | | | | | | | | | | | | | The extent map code was ripped out earlier because of an inability to deal with holes. This patch adds back a simpler caching scheme requiring far less code. Our old extent map caching was designed back when meta data block caching in Ocfs2 didn't work very well, resulting in many disk reads. These days our metadata caching is much better, resulting in no un-necessary disk reads. As a result, extent caching doesn't have to be as fancy, nor does it have to cache as many extents. Keeping the last 3 extents seen should be sufficient to give us a small performance boost on some streaming workloads. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Remember rw lock level during direct ioMark Fasheh2007-04-26
| | | | | | | Cluster locking might have been redone because a direct write won't complete, so this needs to be reflected in the iocb. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Fix up i_blocks calculation to know about holesMark Fasheh2007-04-26
| | | | | | | | Older file systems which didn't support holes did a dumb calculation of i_blocks based on i_size. This is no longer accurate, so fix things up to take actual allocation into account. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Fix extent lookup to return true size of holesMark Fasheh2007-04-26
| | | | | | | | Initially, we had wired things to return a size '1' of holes. Cook up a small amount of code to find the next extent and calculate the number of clusters between the virtual offset and the next allocated extent. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Read from an unwritten extent returns zerosMark Fasheh2007-04-26
| | | | | | | | Return an optional extent flags field from our lookup functions and wire up callers to treat unwritten regions as holes for the purpose of returning zeros to the user. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: make room for unwritten extents flagMark Fasheh2007-04-26
| | | | | | | | | | Due to the size of our group bitmaps, we'll never have a leaf node extent record with more than 16 bits worth of clusters. Split e_clusters up so that leaf nodes can get a flags field where we can mark unwritten extents. Interior nodes whose length references all the child nodes beneath it can't split their e_clusters field, so we use a union to preserve sizing there.

* ocfs2: Use own splice write actorMark Fasheh2007-04-26
| | | | | | | | We need to fill holes during a splice write. Provide our own splice write actor which can call ocfs2_file_buffered_write() with a splice-specific callback. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Use do_sync_mapping_range() in ocfs2_zero_tail_for_truncate()Mark Fasheh2007-04-26

* ocfs2: zero tail of sparse files on truncateMark Fasheh2007-04-26
| | | | | | | | | | Since we don't zero on extend anymore, truncate needs to be fixed up to zero the part of a file between i_size and and end of it's cluster. Otherwise a subsequent extend could expose bad data. This introduced a new helper, which can be used in ocfs2_write(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Teach ocfs2_get_block() about holesMark Fasheh2007-04-26
| | | | | | | | ocfs2_get_block() didn't understand sparse files, fix that. Also remove some code that isn't really useful anymore. We can fix up ocfs2_direct_IO_get_blocks() at the same time. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove ocfs2_prepare_write() and ocfs2_commit_write()Mark Fasheh2007-04-26

* ocfs2: teach ocfs2_file_aio_write() about sparse filesMark Fasheh2007-04-26
| | | | | | | | | | | | Unfortunately, ocfs2 can no longer make use of generic_file_aio_write_nlock() because allocating writes will require zeroing of pages adjacent to the I/O for cluster sizes greater than page size. Implement a custom file write here, which can order page locks for zeroing. This also has the advantage that cluster locks can easily be ordered outside of the page locks.

* ocfs2: abstract out allocation lockingMark Fasheh2007-04-26
| | | | | | | | | | | | | | | | | Right now, file allocation for ocfs2 is done within ocfs2_extend_file(), which is either called from ->setattr() (for an i_size change), or at the top of ocfs2_file_aio_write(). Inodes on file systems with sparse file support will want to do their allocation during the actual write call. In either case the cluster locking decisions are the same. We abstract out that code into a new function, ocfs2_lock_allocators() which will be used by a later patch to enable writing to sparse files. This also provides a nice cleanup of ocfs2_extend_allocation(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: teach extend/truncate about sparse filesMark Fasheh2007-04-26
| | | | | | | | | | | | | | | | | For ocfs2_truncate_file(), we eliminate the "simple" truncate case which no longer exists since i_size is not tied to i_clusters. In ocfs2_extend_file(), we skip the allocation / page zeroing code for file systems which understand sparse files. The core truncate code is changed to do a bottom up tree traversal. This gets abstracted out into it's own function. To make things more readable, most of the special case handling for in-inode extents from ocfs2_do_truncate() is also removed. Though write support for sparse files comes in a later patch, we at least update ocfs2_prepare_inode_for_write() to skip allocation for sparse files.

* ocfs2: temporarily remove extent map cachingMark Fasheh2007-04-26
| | | | | | | | | | | The code in extent_map.c is not prepared to deal with a subtree being rotated between lookups. This can happen when filling holes in sparse files. Instead of a lengthy patch to update the code (which would likely lose the benefit of caching subtree roots), we remove most of the algorithms and implement a simple path based lookup. A less ambitious extent caching scheme will be added in a later patch. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: sparse b-tree supportMark Fasheh2007-04-26
| | | | | | | | | | | | Introduce tree rotations into the b-tree code. This will allow ocfs2 to support sparse files. Much of the added code is designed to be generic (in the ocfs2 sense) so that it can later be re-used to implement large extended attributes. This patch only adds the rotation code and does minimal updates to callers of the extent api. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: small cleanup of ocfs2_request_delete()Mark Fasheh2007-04-26
| | | | | | | | | | | There are two checks in there (one for inode newness, one for other mounted nodes) which are unnecessary, so remove them. The DLM will allow the trylock in either case without any messaging overhead. Removing these makes ocfs2_request_delete() a one liner function, so just move the trylock out one level into ocfs2_query_inode_wipe(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

* ocfs2: Remove delete inode voteTiger Yang2007-04-26
| | | | | | | | | | | Ocfs2 currently does cluster-wide node messaging to check the open state of an inode during delete. This patch removes that mechanism in favor of an inode cluster lock which is taken at shared read when an inode is first read and dropped in clear_inode(). This allows a deleting node to test the liveness of an inode by attempting to take an exclusive lock.

* ocfs2: filter more error printsMark Fasheh2007-04-26
| | | | | | | | | | | We don't want to print anything at all in ocfs2_lookup() when getting an error from ocfs2_iget() - it could be something as innocuous as a signal being detected in the dlm. ocfs2_permission() should filter on -ENOENT which ocfs2_meta_lock() can return if the inode was deleted on another node.

* [PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.
