From 8097531a5cb55c6472118da094dc88caf9be66ac Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 11 Jan 2011 07:24:02 -0500 Subject: cifs: clean up accesses to midCount It's an atomic_t and the code accesses the "counter" field in it directly instead of using atomic_read(). It also is sometimes accessed under a spinlock and sometimes not. Move it out of the spinlock since we don't need belt-and-suspenders for something that's just informational.
