xfs: convert to SPDX license tags Remove the verbose license text from XFS files and replace them with SPDX tags. This does not change the license of any of the code, merely refers to the common, up-to-date license files in LICENSES/ This change was mostly scripted. fs/xfs/Makefile and fs/xfs/libxfs/xfs_fs.h were modified by hand, the rest were detected and modified by the following command: for f in `git grep -l "GNU General" fs/xfs/` ; do echo $f cat $f | awk -f hdr.awk > $f.new mv -f $f.new $f done And the hdr.awk script that did the modification (including detecting the difference between GPL-2.0 and GPL-2.0+ licenses) is as follows: $ cat hdr.awk BEGIN { hdr = 1.0 tag = "GPL-2.0" str = "" } /^ \* This program is free software/ { hdr = 2.0; next } /any later version./ { tag = "GPL-2.0+" next } /^ \*\// { if (hdr > 0.0) { print "// SPDX-License-Identifier: " tag print str print $0 str="" hdr = 0.0 next } print $0 next } /^ \* / { if (hdr > 1.0) next if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 next } /^ \*/ { if (hdr > 0.0) next print $0 next } // { if (hdr > 0.0) { if (str != "") str = str "\n" str = str $0 next } print $0 } END { } $ Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

xfs: quiesce the filesystem after recovery on readonly mount Recently we've had a number of reports where log recovery on a v5 filesystem has reported corruptions that looked to be caused by recovery being re-run over the top of an already-recovered metadata. This has uncovered a bug in recovery (fixed elsewhere) but the vector that caused this was largely unknown. A kdump test started tripping over this problem - the system would be crashed, the kdump kernel and environment would boot and dump the kernel core image, and then the system would reboot. After reboot, the root filesystem was triggering log recovery and corruptions were being detected. The metadumps indicated the above log recovery issue. What is happening is that the kdump kernel and environment is mounting the root device read-only to find the binaries needed to do it's work. The result of this is that it is running log recovery. However, because there were unlinked files and EFIs to be processed by recovery, the completion of phase 1 of log recovery could not mark the log clean. And because it's a read-only mount, the unmount process does not write records to the log to mark it clean, either. Hence on the next mount of the filesystem, log recovery was run again across all the metadata that had already been recovered and this is what triggered corruption warnings. To avoid this problem, we need to ensure that a read-only mount always updates the log when it completes the second phase of recovery. We already handle this sort of issue with rw->ro remount transitions, so the solution is as simple as quiescing the filesystem at the appropriate time during the mount process. This results in the log being marked clean so the mount behaviour recorded in the logs on repeated RO mounts will change (i.e. log recovery will no longer be run on every mount until a RW mount is done). This is a user visible change in behaviour, but it is harmless.

extern void xfs_quiesce_attr(struct xfs_mount *mp);
xfs: xfs_sync_data is redundant. We don't do any data writeback from XFS any more - the VFS is completely responsible for that, including for freeze. We can replace the remaining caller with a VFS level function that achieves the same thing, but without conflicting with current writeback work. This means we can remove the flush_work and xfs_flush_inodes() - the VFS functionality completely replaces the internal flush queue for doing this writeback work in a separate context to avoid stack overruns. This does have one complication - it cannot be called with page locks held. Hence move the flushing of delalloc space when ENOSPC occurs back up into xfs_file_aio_buffered_write when we don't hold any locks that will stall writeback. Unfortunately, writeback_inodes_sb_if_idle() is not sufficient to trigger delalloc conversion fast enough to prevent spurious ENOSPC whent here are hundreds of writers, thousands of small files and GBs of free RAM. Hence we need to use sync_sb_inodes() to block callers while we wait for writeback like the previous xfs_flush_inodes implementation did. That means we have to hold the s_umount lock here, but because this call can nest inside i_mutex (the parent directory in the create case, held by the VFS), we have to use down_read_trylock() to avoid potential deadlocks. In practice, this trylock will succeed on almost every attempt as unmount/remount type operations are exceedingly rare. Note: we always need to pass a count of zero to generic_file_buffered_write() as the previously written byte count. We only do this by accident before this patch by the virtue of ret always being zero when there are no errors. Make this explicit rather than needing to specifically zero ret in the ENOSPC retry case.

[XFS] write barrier support Issue all log sync operations as ordered writes. In addition flush the disk cache on fsync if the sync cached operation didn't sync the log to disk (this requires some additional bookeping in the transaction and log code). If the device doesn't claim to support barriers, the filesystem has an extern log volume or the trial superblock write with barriers enabled failed we disable barriers and print a warning. We should probably fail the mount completely, but that could lead to nasty boot failures for the root filesystem. Not enabled by default yet, needs more destructive testing first.

xfs: fix up inode32/64 (re)mount handling inode32/inode64 allocator behavior with respect to mount, remount and growfs is a little tricky. The inode32 mount option should only enable the inode32 allocator heuristics if the filesystem is large enough for 64-bit inodes to exist. Today, it has this behavior on the initial mount, but a remount with inode32 unconditionally changes the allocation heuristics, even for a small fs. Also, an inode32 mounted small filesystem should transition to the inode32 allocator if the filesystem is subsequently grown to a sufficient size. Today that does not happen. This patch consolidates xfs_set_inode32 and xfs_set_inode64 into a single new function, and moves the "is the maximum inode number big enough to matter" test into that function, so it doesn't rely on the caller to get it right - which remount did not do, previously.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

xfs: Remove icsb infrastructure Now that the in-core superblock infrastructure has been replaced with generic per-cpu counters, we don't need it anymore. Nuke it from orbit so we are sure that it won't haunt us again...

[XFS] kill struct bhv_vfs Now that struct bhv_vfs doesn't have any members left we can kill it and go directly from the super_block to the xfs_mount everywhere.

[XFS] remove dependency of the quota module on behaviors Mount options are now parsed by the main XFS module and rejected if quota support is not available, and there are some new quota operation for the quotactl syscall and calls to quote in the mount, unmount and sync callchains.
