Subject: [PATCH 0/3] count rdev->corrected_errors after final re-read
Date: Wed, 29 Jun 2011 01:47:23 +0900	[thread overview]
Message-ID: <1309279646-4950-1-git-send-email-namhyung@gmail.com> (raw)

Hello,

This patchset tries fix rdev->corrected_errors counting. Read errors
are considered to corrected if write-back and re-read cycle is finished
without further problems. Thus moving the rdev->corrected_errors
counting after the re-reading looks more reasonable IMHO.

For resync case in RAID10, rdev->corrected_errors are increased right
after the first read failure. This seems need an improvement though
it's not handled in this series.

The patches are against 'for-next' branch on git://neil.brown.name/md.

Thanks.
