[PATCH 0/4] btrfs-progs: map-logical: remove the extent check

[Qu Wenruo <wqu@suse.com>]

Commit eb81f8d263ce ("btrfs-progs: map-logical: Rework map-logical
logics") introduced a strict extent item check for btrfs-map-logical.

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
