Subject: [PATCH v2 12/14] io_uring: remove current check from complete_post
Date: Mon, 18 Mar 2024 00:41:57 +0000	[thread overview]
Message-ID: <104a91a59f1c3a1af938ce7c1614f4a3e659bef3.1710720150.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

task_work execution is now always locked, and we shouldn't get into
io_req_complete_post() from them. That means that complete_post() is
always called out of the original task context and we don't even need to
check current.
