Subject: [Qemu-devel] [PATCH v2 05/25] blkdebug: use BlockDriverState's AioContext
Date: Wed,  7 May 2014 12:27:21 +0200	[thread overview]
Message-ID: <1399458461-3997-6-git-send-email-stefanha@redhat.com> (raw)
In-Reply-To: <1399458461-3997-1-git-send-email-stefanha@redhat.com>

Drop the assumption that we're using the main AioContext.  Convert
qemu_bh_new() to aio_bh_new() so we use the BlockDriverState's
AioContext.

The .bdrv_detach_aio_context() and .bdrv_attach_aio_context() interfaces
are not needed since no fd handlers, timers, or BHs stay registered when
requests have been drained.
