Subject: [PATCH 06/29] vfs: add file_pos_unlock() for io_uring usage
Date: Fri, 25 Aug 2023 21:54:08 +0800	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

From: Hao Xu <[email protected]>

Add a helper to unlock f_pos_lock without any condition. Introduce this
since io_uring handles f_pos_lock not with a fd struct, thus
FDPUT_POS_UNLOCK isn't used.
