From a1fde8ee771f92d2a8bbd79532149ddd34546bc1 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 16 Nov 2022 08:49:25 -0500 Subject: [PATCH] cifs: use locks_inode_context helper cifs currently doesn't access i_flctx safely. This requires a smp_load_acquire, as the pointer is set via cmpxchg (a release operation).
