Subject: [PATCH next] cifs: Fix double unlock bug in open_cached_dir()
Date: Mon, 5 May 2025 17:27:20 +0300	[thread overview]
Message-ID: <aBjKyIM-OqMBjFNv@stanley.mountain> (raw)

The "goto out;" also does mutex_unlock(&cfid->cfid_mutex) so delete
this duplicate unlock.

Fixes: 62adfb82c199 ("cifs: serialize initialization and cleanup of cfid")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>

To be honest I suspect that we're going to have to revert
62adfb82c199 ("cifs: serialize initialization and cleanup of cfid")
instead of fixing it?  So this patch might not be worth applying.
