Subject: [PATCHSET RFC 0/5] Poll cleanups and unlocked table removal
Date: Mon, 30 Sep 2024 14:37:44 -0600 [thread overview]
Message-ID: <20240930204018.109617-1-axboe@kernel.dk> (raw)
Hi,
This patchset gets rid of the distinction between the locked and
unlocked hashed cancel table, by simply ensuring that the unlocked
issuer grabs the lock. That then enables us to drop a bunch of code and
helpers (and even a request flag), which is always nice.
Ran this through the usual testing, no issues observed.
