From: Jonathan Brassow Date: Wed, 9 May 2007 09:33:08 +0000 (-0700) Subject: dm raid1: switch rh_in_sync to blocking in do_reads X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b997b82d266c9fb910fc2ad95b9bb93b3bccf9be;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git dm raid1: switch rh_in_sync to blocking in do_reads 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.
