Subject: [md PATCH 30/34] md/raid5: move rdev->corrected_errors counting
Date: Thu, 21 Jul 2011 12:32:28 +1000	[thread overview]
Message-ID: <20110721023228.6728.7610.stgit@notabene.brown> (raw)
In-Reply-To: <20110721022537.6728.90204.stgit@notabene.brown>

From: Namhyung Kim <namhyung@gmail.com>

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.
