* [XFS] remove permission check from xfs_change_file_spaceChristoph Hellwig2008-02-07
| | | | | | | | | | | | | | Both callers of xfs_change_file_space alreaedy do the file->f_mode & FMODE_WRITE check to ensure we have a file descriptor that has been opened for write mode, so there is no need to re-check that with xfs_iaccess. Especially as the later might wrongly deny it for corner cases like file descriptor passing through unix domain sockets.

* [XFS] prevent panic during log recovery due to bogus op_hdr lengthLachlan McIlroy2008-02-07
| | | | | | | | | | | | | | A problem was reported where a system panicked in log recovery due to a corrupt log record. The cause of the corruption is not known but this change will at least prevent a crash for this specific scenario. Log recovery definitely needs some more work in this area.

* [XFS] Remove CFORK macros and use code directly in IFORK and DFORK macros.Christoph Hellwig2008-02-07
| | | | | | | | | | | | | | | | | | | | | Currently XFS_IFORK_* and XFS_DFORK* are implemented by means of XFS_CFORK* macros. But given that XFS_IFORK_* operates on an xfs_inode that embedds and xfs_icdinode_core and XFS_DFORK_* operates on an xfs_dinode that embedds a xfs_dinode_core one will have to do endian swapping while the other doesn't. Instead of having the current mess with the CFORK macros that have byteswapping and non-byteswapping version (which are inconsistantly named while we're at it) just define each family of the macros to stand by itself and simplify the whole matter. A few direct references to the CFORK variants were cleaned up to use IFORK or DFORK to make this possible.

* [XFS] Remove bogus assertNiv Sardi2008-02-07
| | | | | | | | | | | | | | | | This assert is bogus. We can have a forced shutdown occur between the check for the XLOG_FORCED_SHUTDOWN and the ASSERT. Also, the logging system shouldn't care about the state of XFS_FORCED_SHUTDOWN, it should only check XLOG_FORCED_SHUTDOWN. The logging system has it's own forced shutdown flag so, for the case of a forced shutdown that's not due to a logging error, we can flush the log.

* [XFS] optimize XFS_IS_REALTIME_INODE w/o realtime configEric Sandeen2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | Use XFS_IS_REALTIME_INODE in more places, and #define it to 0 if CONFIG_XFS_RT is off. This should be safe because mount checks in xfs_rtmount_init: so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should be encountered after that. Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space, presumeably gcc can optimize around the various "if (0)" type checks: xfs_alloc_file_space -8 xfs_bmap_adjacent -16 xfs_bmapi -8 xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8 <-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4 xfs_qm_vop_chown_reserve -4 SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:30014a Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Signed-off-by: David Chinner <dgc@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

* [XFS] Fix inode allocation latencyDavid Chinner2008-02-07
| | | | | | | | | | | | | | | | | | | | | | The log force added in xfs_iget_core() has been a performance issue since it was introduced for tight loops that allocate then unlink a single file. under heavy writeback, this can introduce unnecessary latency due tothe log I/o getting stuck behind bulk data writes. Fix this latency problem by avoinding the need for the log force by moving the place we mark linux inode dirty to the transaction commit rather than on transaction completion. This also closes a potential hole in the sync code where a linux inode is not dirty between the time it is modified and the time the log buffer has been written to disk.

* [XFS] Fix transaction overrun during writeback.David Chinner2008-02-07
| | | | | | | | | | | | | | | | | | | Prevent transaction overrun in xfs_iomap_write_allocate() if we race with a truncate that overlaps the delalloc range we were planning to allocate. If we race, we may allocate into a hole and that requires block allocation. At this point in time we don't have a reservation for block allocation (apart from metadata blocks) and so allocating into a hole rather than a delalloc region results in overflowing the transaction block reservation. Fix it by only allowing a single extent to be allocated at a time.

* [XFS] Fix sparse warning in xlog_recover_do_efd_trans.David Chinner2008-02-07
| | | | | | | | | | | | | | | | Sparse trips over the locking order in xlog_recover_do_efd_trans() when xfs_trans_delete_ail() drops the ail lock. Because the unlock is conditional, we need to either annotate with a "fake unlock" or change the structure of the code so sparse thinks the function always unlocks. Reordering the code makes it simpler, so do that.

* [XFS] Make xfs_bulkstat() to report unlinked but referenced inodesVlad Apostolov2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | We need xfs_bulkstat() to report inode stat for inodes with link count zero but reference count non zero. The fix here: http://oss.sgi.com/archives/xfs/2007-09/msg00266.html changed this behavior and made xfs_bulkstat() to filter all unlinked inodes including those that are not destroyed yet but held by reference. The attached patch returns back to the original behavior by marking the on-disk inode buffer "dirty" when di_mode is cleared (at that time both inode link and reference counter are zero).

* [XFS] fix 32-bit compat ioctls for GETXFLAGS, SETXFLAGS, GETVERSIONEric Sandeen2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | XFS_IOC_GETVERSION, XFS_IOC_GETXFLAGS and XFS_IOC_SETXFLAGS all take a "long" which changes size between 32 and 64 bit platforms. So, the ioctl cmds that come in from a 32-bit app aren't as expected, for example on GETXFLAGS, unknown cmd fd(3) cmd(80046601){t:'f';sz:4} due to the size mismatch. So, use instead the 32-bit version of the commands for compat ioctls, and other than that it doesn't take any more manipulation. Also, for both native and compat versions, just define them to the values as defined in fs.h SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:29849a Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com> Signed-off-by: Tim Shimmin <tes@sgi.com>

* [XFS] Refactor xfs_mountfsEric Sandeen2008-02-07
| | | | | | | | | | | | | | | | | | | | Refactoring xfs_mountfs() to call sub-functions for logical chunks can help save a bit of stack, and can make it easier to read this long function. The mount path is one of the longest common callchains, easily getting to within a few bytes of the end of a 4k stack when over lvm, quotas are enabled, and quotacheck must be done. With this change on top of the other stack-related changes I've sent, I can get xfs to survive a normal xfsqa run on 4k stacks over lvm.

* [XFS] kill unnessecary ioops indirectionLachlan McIlroy2008-02-07
| | | | | | | | | | | | | | | Currently there is an indirection called ioops in the XFS data I/O path. Various functions are called by functions pointers, but there is no coherence in what this is for, and of course for XFS itself it's entirely unused. This patch removes it instead and significantly reduces source and binary size of XFS while making maintaince easier.

* [XFS] simplify vn_revalidateChristoph Hellwig2008-02-07
| | | | | | | | | | | | | | | No need to allocate a bhv_vattr_t on stack and call xfs_getattr to update a few fields in the Linux inode from the XFS inode, just do it directly. And yes, this function is in dire need of a better name and prototype, I'll do in a separate patch, though.

* [XFS] kill BMAPI_UNWRITTENChristoph Hellwig2008-02-07
| | | | | | | | | | | | | | | There is no reason to go through xfs_iomap for the BMAPI_UNWRITTEN because it has nothing in common with the other cases. Instead check for the shutdown filesystem in xfs_end_bio_unwritten and perform a direct call to xfs_iomap_write_unwritten (which should be renamed to something more sensible one day) SGI-PV: 970241 SGI-Modid: xfs-linux-melb:xfs-kern:29681a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Donald Douwsma <donaldd@sgi.com> Signed-off-by: Tim Shimmin <tes@sgi.com>
