[PATCH 0/2] btrfs: fixes for commit 947a629988f1 ("btrfs: move tree block parentness check into validate_extent_buffer()")

[Qu Wenruo <wqu@suse.com>]

There is a regression report from Mikhail that his btrfs RAID0 fs
randomly flips to RO after commit 947a629988f1.

It turns out that, the offending commit can not handle tree blocks
crossing stripe boundary.

Although tree blocks crossing stripe boundary is not an ideal situation,
we should still be able to correctly handle it.

This patchset firstly adds the missing level mismatch error message,
then fix the offending commit.

Qu Wenruo (2):
  btrfs: add error message for metadata level mismatch
  btrfs: fix the false alert on bad tree level
