From f2b9857eee17797541b845782ade4d7a9d50f843 Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Sun, 18 May 2008 15:32:43 -0600 Subject: Add a bunch of cycle_kernel_lock() calls All of the open() functions which don't need the BKL on their face may still depend on its acquisition to serialize opens against driver initialization. So make those functions acquire then release the BKL to be on the safe side.
