Subject: [PATCH 6/6] block/iscsi: Do not force-cap *pnum
Date: Thu, 17 Jun 2021 17:52:47 +0200	[thread overview]
Message-ID: <20210617155247.442150-7-mreitz@redhat.com> (raw)
In-Reply-To: <20210617155247.442150-1-mreitz@redhat.com>

bdrv_co_block_status() does it for us, we do not need to do it here.

The advantage of not capping *pnum is that bdrv_co_block_status() can
cache larger data regions than requested by its caller.
