* [XFS] kill xfs_freeze.Christoph Hellwig2008-02-07
| | | | | | | | | | | No need to have a wrapper just two call two more functions. SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:29816a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Donald Douwsma <donaldd@sgi.com> Signed-off-by: Tim Shimmin <tes@sgi.com>
* [XFS] cleanup vnode useage in xfs_iget.cChristoph Hellwig2008-02-07

* [XFS] cleanup vnode useage in xfs_ioctl.cChristoph Hellwig2008-02-07
| | | | | | | | | | | | | xfs_ioctl.c passes around vnode pointers quite a lot, but all places already have the Linux inode which is identical to the vnode these days. Clean the code up to always use the Linux inode.

* [XFS] Kill off xfs_statvfs.Christoph Hellwig2008-02-07
| | | | | | | | | | | | | | | | | We were already filling the Linux struct statfs anyway, and doing this trivial task directly in xfs_fs_statfs makes the code quite a bit cleaner. While I was at it I also moved copying attributes that don't change over the lifetime of the filesystem outside the superblock lock. xfs_fs_fill_super used to get the magic number and blocksize through xfs_statvfs, but assigning them directly is a lot cleaner and will save some stack space during mount.

* [XFS] kill xfs_iocore_tChristoph Hellwig2008-02-07
| | | | | | | | | | | | | | | xfs_iocore_t is a structure embedded in xfs_inode. Except for one field it just duplicates fields already in xfs_inode, and there is nothing this abstraction buys us on XFS/Linux. This patch removes it and shrinks source and binary size of xfs aswell as shrinking the size of xfs_inode by 60/44 bytes in debug/non-debug builds.

| | | | | | | | | | | | | | | Currently there is an indirection called ioops in the XFS data I/O path.

| | | | | | | | | | | | | | | | | | This was broken by my '[XFS] simplify xfs_create/mknod/symlink prototype', which assigned the re-shuffled ondisk dev_t back to the rdev variable in xfs_vn_mknod. Because of that i_rdev is set to the ondisk dev_t instead of the linux dev_t later down the function. Fortunately the fix for it is trivial: we can just remove the assignment because xfs_revalidate_inode has done the proper job before unlocking the inode.

| | | | | | | | | | | | | | | | The recent filldir regression fix was not putting the correct d_off in each dirent. This was resulting in incorrect cookies being passed to dmapi ioctls and the wrong offset appearing in the dirents. readdir was unaffected as the filp->f_pos was being updated with the correct offset and this was being written into the last dirent in each buffer.

* [XFS] Don't wait for pending I/Os when purging blocks beyond eof.Lachlan McIlroy2007-12-18
| | | | | | | | | | | | | | | On last close of a file we purge blocks beyond eof. The same code is used when we truncate the file size down. In this case we need to wait for any pending I/Os for dirty pages beyond the new eof. For the last close case we are not changing the file size and therefore do not need to wait for any I/Os to complete. This fixes a performance bottleneck where writes into the page cache and cache flushes can become mutually exclusive.

| * [XFS] Fix broken inode cluster setup.David Chinner2007-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The radix tree based inode caches did away with the inode cluster hashes, replacing them with a bunch of masking and gang lookups on the radix tree. This masking got broken when moving the code to per-ag radix trees and indexing by agino # rather than straight inode number. The result is clustered inode writeback does not cluster and things can go extremely slowly when there are lots of inodes to write. Fix it up by comparing the agino # of the inode we just looked up to the index of the cluster we are looking for.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - calculation of 'page_count' was incorrect as it did not consider the offset of 'mem' into the first page.

Set it to the total length of the buffer. - I suspect that passing a non-aligned address into mem_to_page() for the first page may have been causing issues - don't know but just tidy up that code anyway.

This special case causes bulkstat to fail because the special case uses xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions have different semantics. xfs_bulkstat() will return the next inode after the one supplied while skipping internal inodes (ie quota inodes). xfs_bulkstate_single() will only lookup the inode supplied and return an error if it is an internal inode. - in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied so in cases were we return without examining any inodes the scan wont restart back at zero. - sanity check for valid *ubcountp values. Cannot sanity check for valid ubuffer here because some users of xfs_bulkstat() don't supply a buffer. - checks against 'ubleft' (the space left in the user's buffer) should be against 'statstruct_size' which is the supplied minimum object size. The mixture of checks against statstruct_size and 0 was one of the reasons we were skipping inodes. - if the formatter function returns BULKSTAT_RV_NOTHING and an error and the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT is for inodes that are no longer valid and we just skip them. EINVAL is returned if we try to lookup an internal inode so we skip them too. For a DMF scan if the inode and DMF attribute cannot fit into the space left in the user's buffer it would return ERANGE. We didn't handle this error and skipped the inode. We would continue to skip inodes until one fitted into the user's buffer or we completed the scan. - put back the recalculation of agino (that got removed with the last fix) at the end of the while loop. This is because the code at the start of the loop expects agino to be the last inode examined if it is non-zero. - if we found some inodes but then encountered an error, return success this time and the error next time. If the formatter aborted with ENOMEM we will now return this error but only if we couldn't read any inodes. Previously if we encountered ENOMEM without reading any inodes we returned a zero count and no error which falsely indicated the scan was complete.

|/ | | | | | | | | | | | | | | This one is a lot more complicated than the previous ones. XFS already had a very clever scheme for supporting 64bit inode numbers in filehandles, and I've reworked this to be some kind of a prototype for the generic 64bit inode filehandle support.

* [XFS] cleanup fid types messChristoph Hellwig2007-10-19
| | | | | | | | | | | | | | | | | | Currently XFs has three different fid types: struct fid, struct xfs_fid and struct xfs_fid2 with hte latter two beeing identicaly and the first one beeing the same size but an unstructured array with the same size. This patch consolidates all this to alway uuse struct xfs_fid. This patch is required for an upcoming patch series from me that revamps the nfs exporting code and introduces a Linux-wide struct fid.

| * [XFS] eagerly remove vmap mappings to avoid upsetting XenJeremy Fitzhardinge2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XFS leaves stray mappings around when it vmaps memory to make it virtually contigious. This upsets Xen if one of those pages is being recycled into a pagetable, since it finds an extra writable mapping of the page. This patch solves the problem in a brute force way, by making XFS always eagerly unmap its mappings.

| | | | | | | | | | | | | | | | | | | | | | Because we cherrypicked SGI-Modid xfs-linux-melb:xfs-kern:29675a and it depended on the sgi mod which removed io_vnode (which was not cherrypicked in 23) it was hand modified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Put back the QUEUE_ORDERED_NONE test which caused us grief in sles when it was taken out as, IIRC, it allowed md/lvm to be thought of as supporting barriers when they weren't in some configurations.

| * [XFS] avoid race in sync_inodes() that can fail to write out all dirty dataLachlan McIlroy2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In xfs_fs_sync_super() treat a sync the same as a filesystem freeze. This is needed to force the log to disk for inodes which are not marked dirty in the Linux inode (the inodes are marked dirty on completion of the log I/O) and so sync_inodes() will not flush them. In xfs_fs_write_inode() a synchronous flush will not get an EAGAIN from xfs_inode_flush() and if an asynchronous flush returns EAGAIN we should pass it on to the caller. If we get an error while flushing the inode then re-dirty it so we can try again later.
