From: Liu Bo Date: Tue, 16 May 2017 00:20:07 +0000 (-0700) Subject: Btrfs: record error if one block has failed to retry X-Git-Tag: v4.13-rc1~150^2~99 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=629ebf4fadbc647e2118ef9c94b038eeef178e9c;p=linux.git Btrfs: record error if one block has failed to retry In the nocsum case of dio read endio, it returns immediately if an error gets returned when repairing, which leaves the rest blocks unrepaired. The behavior is different from how buffered read endio works in the same case. This changes it to record error only and go on repairing the rest blocks.
