From e9fd939654f17651ff65e7e55aa6934d29eb4335 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Wed, 4 Mar 2020 16:14:12 +0300 Subject: io_uring/io-wq: forward submission ref to async First it changes io-wq interfaces. It replaces {get,put}_work() with free_work(), which guaranteed to be called exactly once. It also enforces free_work() callback to be non-NULL. io_uring follows the changes and instead of putting a submission reference in io_put_req_async_completion(), it will be done in io_free_work(). As removes io_get_work() with corresponding refcount_inc(), the ref balance is maintained.
