From 0c842ad46a51891ac4420b7285613f4134a65ccd Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 8 Jul 2011 14:36:19 +0200 Subject: xfs: clean up buffer locking helpers Rename xfs_buf_cond_lock and reverse it's return value to fit most other trylock operations in the Kernel and XFS (with the exception of down_trylock, after which xfs_buf_cond_lock was modelled), and replace xfs_buf_lock_val with an xfs_buf_islocked for use in asserts, or and opencoded variant in tracing. remove the XFS_BUF_* wrappers for all the locking helpers.
