Subject: [dm-devel] [5.20 PATCH v3 0/2] dm: improve bio splitting at expense of requeue complexity
Date: Wed, 6 Jul 2022 13:44:01 -0400 [thread overview]
Message-ID: <20220706174403.79317-1-snitzer@kernel.org> (raw)
This v3 moves all bio_rewind() code to drivers/md/dm-io-rewind.c for
exclussive use by DM core's dm_io requeue support via dm_io_rewind().
It was determined that block core doesn't need to expose bio_rewind()
for more general use. If/when that changes we can revisit, armed with
the understanding of how DM's use of bio_rewind() has faired.
These changes are now staged for 5.20 inclussion via linux-dm.git
