Before this patch, btrfs check can only repair bad free space cache
inode mode (as it was the first case detected by tree-checker and reported)
But now what may happen finally happened, we have user reorting bad
inode mode in subvolumes trees.
Although the reported get the fs fixed by removing the offending old
files, it's still a bad thing that "btrfs check" can't fix it.
This patch will bring the repair functionality to all inodes, along with
needed test image.
Qu Wenruo (4):
btrfs-progs: check/common: Make repair_imode_common() to handle inodes
in subvolume trees
btrfs-progs: check/lowmem: Repair bad imode early
btrfs-progs: check/original: Fix inode mode in subvolume trees
btrfs-progs: tests/fsck: Add new images for inode mode repair
