From 579aa9caf552c639fc78168db4cfe7ffcf00c3b3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 22 Apr 2008 17:34:00 +1000 Subject: [XFS] shrink mrlock_t The writer field is not needed for non_DEBU builds so remove it. While we're at i also clean up the interface for is locked asserts to go through and xfs_iget.c helper with an interface like the xfs_ilock routines to isolated the XFS codebase from mrlock internals. That way we can kill mrlock_t entirely once rw_semaphores grow an islocked facility. Also remove unused flags to the ilock family of functions.
