Subject: [PATCHSET 0/2] io_uring: close lookup gap for dependent work
Date: Wed, 20 Nov 2019 13:09:28 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
As discussed earlier today on this list, there's a gap between finding
dependent work and ensuring we can look it up for cancellation purposes.
On top of that, we also currently NEVER find dependent work due to how
we do lookups of it, so that is fixed in patch 1 while patch 2
implements the fix for the lookup gap.
Patches are against for-5.5/io_uring-post
