From d92a8d48085df863032110d9ccb221cde98d14e1 Mon Sep 17 00:00:00 2001
From: Steven Whitehouse <swhiteho@redhat.com>
Date: Mon, 27 Feb 2006 10:57:14 -0500
Subject: [GFS2] Audit printk and kmalloc

All printk calls now have KERN_ set where required and a couple of
kmalloc(), memset(.., 0, ...) calls changed to kzalloc().

This is in response to comments from:
Pekka Enberg <penberg@cs.helsinki.fi> and
Eric Sesterhenn <snakebyte@gmx.de>

Subject: [GFS2] Fix gfs_ prefix in locking.c

The previous patch didn't change all the gfs_ to gfs2_ so
this is the remainder.

From e9fc2aa091ab8fa46e60d4c9d06a89305c441652 Mon Sep 17 00:00:00 2001

Subject: [GFS2] Update copyright, tidy up incore.h

As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this
updates the copyright message to say "version" in full rather than
"v.2". Also incore.h has been updated to remove forward structure
declarations which are not required.

The gfs2_quota_lvb structure has now had endianess annotations added
to it. Also quota.c has been updated so that we now store the
lvb data locally in endian independant format to avoid needing
a structure in host endianess too. As a result the endianess
conversions are done as required at various points and thus the
conversion routines in lvb.[ch] are no longer required. I've
moved the one remaining constant in lvb.h thats used into lm.h
and removed the unused lvb.[ch].

I have not changed the HIF_ constants. That is left to a later patch
which I hope will unify the gh_flags and gh_iflags fields of the
struct gfs2_holder.

Subject: [GFS2] Tidy up locking code

As per Jan Engelhardt's second email, this removes some unused code,
and fixes up indenting in various places.

Subject: [GFS2] Remove one typedef

This removes one of the typedefs from the locking interface. It
is replaced by a forward declaration of the gfs2 superblock. The
other two are not so easy to solve since in their case, they
can refer to one of two possible structures.

Subject: [GFS2] Use void * instead of typedef for locking module interface

As requested by Jan Engelhardt, this removes the typedefs in the
locking module interface and replaces them with void *. Also
since we are changing the interface, I've added a few consts
as well.

From 7d308590ae60d1f038a54a94e78a385c5c163452 Mon Sep 17 00:00:00 2001

Subject: [GFS2] Export lm_interface to kernel headers

lm_interface.h has a few out of the tree clients such as GFS1
and userland tools.

Right now, these clients keeps a copy of the file in their build tree
that can go out of sync.

Move lm_interface.h to include/linux, export it to userland and
clean up fs/gfs2 to use the new location.

- * LM_FLAG_NOEXP
- * GFS sets this flag on lock requests it makes while doing journal recovery.
- * These special requests should not be blocked due to the recovery like
- * ordinary locks would be.
- *
- * LM_FLAG_ANY
- * A SHARED request may also be granted in DEFERRED, or a DEFERRED request may
- * also be granted in SHARED.  The preferred state is whichever is compatible
- * with other granted locks, or the specified state if no other locks exist.
- *
- * LM_FLAG_PRIORITY
- * Override fairness considerations.  Suppose a lock is held in a shared state
- * and there is a pending request for the deferred state.  A shared lock
- * request with the priority flag would be allowed to bypass the deferred
- * request and directly join the other shared lock.  A shared lock request
- * without the priority flag might be forced to wait until the deferred
- * requested had acquired and released the lock.
