From b0991aa324b57dca8feef75ed75b24080ee4a9fc Mon Sep 17 00:00:00 2001 From: Jan Blunck Date: Wed, 24 Feb 2010 13:25:29 +0100 Subject: BKL: Remove BKL from CifsFS The BKL is only used in put_super and fill_super that are both protected by the superblocks s_umount rw_semaphore. Therefore it is safe to remove the BKL entirely.
