Subject: [PATCH] nbd: set the max segment size to UINT_MAX
Date: Tue, 18 Apr 2017 16:22:51 -0400	[thread overview]
Message-ID: <1492546971-2682-1-git-send-email-jbacik@fb.com> (raw)

NBD doesn't care about limiting the segment size, let the user push the
largest bio's they want.  This allows us to control the request size
solely through max_sectors_kb.
