This patch changes the last user of recursive locking so that it no longer needs this feature and removes it from the glock layer. This makes the glock code a lot simpler and easier to understand. Its also a prerequsite to adding support for the AOP_TRUNCATED_PAGE return code (or at least it is if you don't want your brain to melt in the process) I've left in a couple of checks just in case there is some place else in the code which is still using this feature that I didn't spot yet, but they can probably be removed long term.

At some stage, a mutex was added to gfs2_glock_put() without checking all its call sites. Two of them were called from under a spinlock causing random delays at various points and crashes. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

When allocating memory to sort directory entries, use vmalloc() rather than kmalloc() since for larger directories, the required size can easily be graeter than the 128k maximum of kmalloc(). Also adding the first steps towards getting the AOP_TRUNCATED_PAGE return code get in the glock code by flagging all places where we request a glock and we are holding a page lock.

Update the debugging code in trans.c and at the same time improve the debugging code for gfs2_holders. The new code should be pretty fast during the normal case and provide just as much information in case of errors (or more). One small function from glock.c has moved to glock.h as a static inline so that its return address won't get in the way of the debugging. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

As suggested by Pekka Enberg <penberg@cs.helsinki.fi>. The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h The other macros are gone from gfs2.h as (although not requested by Pekka Enberg) are a number of included header file which are now included individually. The inode number comparison function is now an inline function. The DT2IF and IF2DT may be addressed in a future patch. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

As well as a number of minor bug fixes, this patch changes GFS to use mutices rather than semaphores. This results in better information in case there are any locking problems. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>
