* [XFS] Implement fallocate.David Chinner2008-02-071-0/+43

* [XFS] Fix inode allocation latencyDavid Chinner2008-02-075-51/+23Star
| | | | | | | | | | | | | | | | | | | | | | 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 Chinner2008-02-071-25/+50
| | | | | | | | | | | | | | | | | | | 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 Chinner2008-02-071-11/+3Star
| | | | | | | | | | | | | | | | 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 Apostolov2008-02-072-20/+27
| | | | | | | | | | | | | | | | | | | | | | | 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 Sandeen2008-02-072-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Sandeen2008-02-071-105/+162
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Simplify vnode tracing calls by embedding function name & return addr in the calling macro. Also do a lot of vnode->inode renaming for consistency, while we're at it.

* [XFS] remove dead SYNC_BDFLUSH case in xfs_sync_inodesLachlan McIlroy2008-02-071-175/+23Star
| | | | | | | | | | | | | A large part of xfs_sync_inodes is conditional on the SYNC_BDFLUSH which is never passed to it. This patch removes it and adds an assert that triggers in case some new code tries to pass SYNC_BDFLUSH to it.

It drops the INT_* definitions as they are no longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_* macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between standard EB and EB + the ARM11MPCore tile. The platform.h file contains common definitions to the RealView platforms and it is only directly included in board-*.h files.
