Subject: [PATCH md 003 of 10] Make sure a user-request sync of raid5 ignores intent bitmap
Date: Wed, 2 Nov 2005 21:15:05 +1100 [thread overview]
Message-ID: <1051102101505.23874@suse.de> (raw)
In-Reply-To: 20051102205640.22689.patches@notabene
A sync of raid5 usually ignore blocks which the bitmap says are in-sync.
But a user-request check or repair should not ignore these.
