Date: Tue, 8 May 2007 20:49:17 +0100 From: Alasdair G Kergon <agk@...hat.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: dm-devel@...hat.com, linux-kernel@...r.kernel.org, Jonathan Brassow <jbrassow@...hat.com> Subject: [2.6.22 PATCH 25/26] dm raid1: switch rh_in_sync to blocking in do_reads From: Jonathan Brassow <jbrassow@...hat.com> The call to rh_in_sync() in do_reads() should be allowed to block. It is in the mirror worker thread which already permits blocking operations. This will be needed to support clustered mirroring which will perform network operations.
