It not only makes it harder to use btrfs-map-logical, but also prevents btrfs-map-logical to handle fs with corrupted extent tree. This patchset will address the behavior by completely removing the extent item check, and allow btrfs-map-logical to work on fs with corrupted extent tree. Since we're here, also change the default mapping length to sectorsize, and reject any unaligned logical/bytes pair. Qu Wenruo (4): btrfs-progs: map-logical: use sectorsize as default size btrfs-progs: map-logical: reject unaligned logical/bytes pair btrfs-progs: map-logical: loosen the required trees to open the filesystem btrfs-progs: map-logical: remove the extent item check btrfs-map-logical.c | 158 +++++--------------------------------------- 1 file changed, 17 insertions(+), 141 deletions(-) -- 2.32.0
