Subject: Btrfs: remove some WARN_ONs in the IO failure path
X-Git-Tag: firefly_0821_release~14037^2~5
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cc7b0c9b701a079016183f3546b4d720194b367f;p=firefly-linux-kernel-4.4.55.git

Btrfs: remove some WARN_ONs in the IO failure path

These debugging WARN_ONs make too much console noise during regular
IO failures.  An IO failure will still generate a number of messages
as we verify checksums etc, but these two are not needed.
