[PATCH 0/2] btrfs-progs: add new precaution check for incoming subpage support

[Qu Wenruo <wqu@suse.com>]

For the incoming subpage support, we need to ensure no tree block could
cross 64K page boundary.

Currently both kernel and btrfs-progs won't create such tree blocks, but
still add such check as non-critical warning to catch any ancient btrfs
in the wild.

Also enhance the existing test cases to catch the warning message just
in case we miss something.

Qu Wenruo (2):
  btrfs-progs: check: detect and warn about tree blocks cross 64K page
    boundary
  btrfs-progs: tests: check the result log for critical warnings
