From 3685c2a1d773781608c9e281a6ff6b4c8ea8f6f9 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 11 Oct 2007 17:42:32 +1000 Subject: [XFS] Unwrap XFS_SB_LOCK. Un-obfuscate XFS_SB_LOCK, remove XFS_SB_LOCK->mutex_lock->spin_lock macros, call spin_lock directly, remove extraneous cookie holdover from old xfs code, and change lock type to spinlock_t.
