Filipe Manana a3baaf0d78 Btrfs: fix fsync after succession of renames and unlink/rmdir ... After a succession of renames operations of different files and unlinking one of them, if we fsync one of the renamed files we can end up with a log that will either fail to replay at mount time or result in a filesystem that is in an inconsistent state. One example scenario: $ mkfs.btrfs -f /dev/sdb $ mount /dev/sdb /mnt $ mkdir /mnt/testdir $ touch /mnt/testdir/fname1 $ touch /mnt/testdir/fname2 $ sync $ mv /mnt/testdir/fname1 /mnt/testdir/fname3 $ rm -f /mnt/testdir/fname2 $ ln /mnt/testdir/fname3 /mnt/testdir/fname2 $ touch /mnt/testdir/fname1 $ xfs_io -c "fsync" /mnt/testdir/fname1 <power failure> $ mount /dev/sdb /mnt $ umount /mnt $ btrfs check /dev/sdb [1/7] checking root items [2/7] checking extents [3/7] checking free space cache [4/7] checking fs roots root 5 inode 259 errors 2, no orphan item ERROR: errors found in fs roots Opening filesystem to check... Checking filesystem on /dev/sdc UUID: 20e4abb8-5a19-4492-8bb4-6084125c2d0d found 393216 bytes used, error(s) found total csum bytes: 0 total tree bytes: 131072 total fs tree bytes: 32768 total extent tree bytes: 16384 btree space waste bytes: 122986 file data blocks allocated: 262144 referenced 262144 On a kernel without the first patch in this series, titled "[PATCH] Btrfs: fix fsync after succession of renames of different files", we get instead an error when mounting the filesystem due to failure of replaying the log: $ mount /dev/sdb /mnt mount: mount /dev/sdb on /mnt failed: File exists Fix this by logging the parent directory of an inode whenever we find an inode that no longer exists (was unlinked in the current transaction), during the procedure which finds inodes that have old names that collide with new names of other inodes. A test case for fstests follows soon.
