* kill I_LOCKChristoph Hellwig2009-12-17

* fold do_sync_file_range into sys_sync_file_rangeChristoph Hellwig2009-12-17
| | | | | | | | | | | | We recently go rid of all callers of do_sync_file_range as they're better served with vfs_fsync or the filemap_write_and_wait. Now that do_sync_file_range is down to a single caller fold it into it so that people don't start using it again accidentally. While at it also switch it from using __filemap_fdatawrite_range(..., WB_SYNC_ALL) to the more clear filemap_fdatawrite_range().

* fs: no games with DCACHE_UNHASHEDNick Piggin2009-12-17
| | | | | | | | | | | | | | | Filesystems outside the regular namespace do not have to clear DCACHE_UNHASHED in order to have a working /proc/$pid/fd/XXX. Nothing in proc prevents the fd link from being used if its dentry is not in the hash. Also, it does not get put into the dcache hash if DCACHE_UNHASHED is clear; that depends on the filesystem calling d_add or d_rehash. So delete the misleading comments and needless code.

| * XFS: Free buffer pages array unconditionallyDave Chinner2009-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in xfs_free_buf() only attempts to free the b_pages array if the buffer is a page cache backed or page allocated buffer. The extra log buffer that is used when the log wraps uses pages that are allocated to a different log buffer, but it still has a b_pages array allocated when those pages are associated to with the extra buffer in xfs_buf_associate_memory. Hence we need to always attempt to free the b_pages array when tearing down a buffer, not just on buffers that are explicitly marked as page bearing buffers. This fixes a leak detected by the kernel memory leak code. Signed-off-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Alex Elder <aelder@sgi.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change all async metadata buffers to use [READ|WRITE]_META I/O types so that the I/O doesn't get issued immediately. This allows merging of adjacent metadata requests but still prioritises them over bulk data. This shows a 10-15% improvement in sequential create speed of small files. Don't include the log buffers in this classification - leave them as sync types so they are issued immediately.

The most complicated one is DIO_OWN_LOCKING for reads, which happens to not actually be used. This patch gets rid of the DIO_OWN_LOCKING - as mentioned above the read case is unused anyway, and the write side is almost identical to DIO_NO_LOCKING. The difference is that DIO_NO_LOCKING always sets the create argument for the get_blocks callback to zero, but we can easily move that to the actual get_blocks callbacks. There are four users of the DIO_NO_LOCKING mode: gfs already ignores the create argument and thus is fine with the new version, ocfs2 only errors out if create were ever set, and we can remove this dead code now, the block device code only ever uses create for an error message if we are fully beyond the device which can never happen, and last but not least XFS will need the new behavour for writes. Now we can replace the lock_type variable with a flags one, where no flag means the DIO_NO_LOCKING behaviour and DIO_LOCKING is kept as the first flag. Separate out the check for not allowing to fill holes into a separate flag, although for now both flags always get set at the same time. Also revamp the documentation of the locking scheme to actually make sense. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

This allows using the same methods for multiple handlers, e.g. for the ACL methods which perform exactly the same action for the access and default ACLs, just using a different underlying attribute. With a little more groundwork it'll also allow sharing the methods for the regular user/trusted/secure handlers in extN, ocfs2 and jffs2 like it's already done for xfs in this patch. Also change the inode argument to the handlers to a dentry to allow using the handlers mechnism for filesystems that require it later, e.g. cifs.

This causes __follow_link to skip calling __vfs_follow_link and so the dentry isn't revalidated. This is a problem when the link target sits on NFSv4 as it depends on the VFS to revalidate the dentry before using it on an open call. Ensure that this occurs by forcing a revalidation of the target dentry of LAST_BIND symlinks. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-by: "Eric W.

The calls to nfs4_end_drain_session() from the main loop in nfs4_state_manager() Oops due to the lack of an NFSv4.1 session when running NFSv4.0. The fix is to move those two calls back into nfs41_init_clientid() and nfs4_reset_session(). The calls to nfs4_end_drain_session() that remain inside nfs4_state_manager() are safe, since the NFSv4.0 code will never set the NFS4CLNT_SESSION_DRAINING bit.
