Subject: [PATCH 8/8] io_uring: keep interrupts on on submit completion
Date: Mon, 25 Jan 2021 11:42:27 +0000 [thread overview]
Message-ID: <1645f7f935aa833231ebaad974bc37890ad9a2e3.1611573970.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
We don't call io_submit_flush_completions() in interrupt context, no
need to use irq* versions of spinlock.
