btrfs-progs: tests: test for FST corruption detection/repair
This set fixes bugs of checking unaligned disk_bytenr extent_data and
orphan extent. Lowmem part patches can be used in common, so I put
this two fixes together.
For unaligned disk_bytenr extent_data, now original and lowmem check
both delete the corrupted part and punch a hole.
For orphan extent, lowmem mode has no change here.
Original mode discards function of detect and repair orphan extents
according extent items. Because as corruptions the community reported,
extent tree is more problematic than fs trees.
patch[1-2] fix minor bugs in lowmem repair.
patch[3] fixes false alert about repaired extent item in lowmem mode.
patch[4] fixes annoying alerts about gap in file extent in lowmem mode.
patch[5,6,7] enable check and repair unaligned disk_bytenr file extent
in lowmem mode.
patch[8,9] revert support for orphan extent in original mode.
patch[10] fixes bug about finding right backrefs in original mode.
patch[11] adds support to detect and delete unaligned file extents
in original.
patch[12] adds a test image which lacks of a file extent.
patch[13] enables lowmem repair of test case fsck-tests/001 which has
unaligned disk_bytenr file extent.
