Subject: [PATCH 3/7] cifs: use locks_inode_context helper
Date: Wed, 16 Nov 2022 10:17:22 -0500 [thread overview]
Message-ID: <20221116151726.129217-4-jlayton@kernel.org> (raw)
In-Reply-To: <20221116151726.129217-1-jlayton@kernel.org>
cifs currently doesn't access i_flctx safely. This requires a
smp_load_acquire, as the pointer is set via cmpxchg (a release
operation).
