Subject: [PATCHSET 0/3] io_uring improvements
Date: Fri, 15 Mar 2019 08:59:35 -0600 [thread overview]
Message-ID: <20190315145938.21516-1-axboe@kernel.dk> (raw)
This is on top of the just posted "PATCHSET v2 0/7] io_uring fixes"
series.
This re-introduces the ability to NOT have to touch page reference
counts for our fixed buffers. Instead of assuming that's always
safe to do with a BVEC iter, we add an explicit flag for that. This
shifts the iter types a bit, but otherwise shouldn't cause any
changes.
The final patch re-adds the "we hit cache" flag. I left this out of
the initial series due to concerns over informing userspace about
this, with all the mincore etc discussions.
