Cover letter [PATCH v3 0/6] btrfs-progs: check: Detect invalid dev extents and device items
This patchset can be fetch from github:
https://github.com/adam900710/btrfs-progs/tree/dev_extents_check
Hans van Kranenburg reported a case where btrfs DUP chunk allocator could allocate invalid dev extents, either overlaps with existing dev extents or beyond device boundary.
This patchset enhances the btrfs-progs side to detect such problems. With hand crafted test image for it.
Changelog:
v2:
Fix a bug in the 1st patch which makes lowmem mode never checks overlap dev extents.
Fix test case bug which never passes due to wrong script.
v3:
Add btrfs-image fixes to make test cases happy.
