Hey all -

Now that the 2.6.0 hurdle has been cleared and Linus seems to be more
open to cleanup-type patches, I have these to submit for comment.

I have 4 patches, descriptions follow:
* cleanup-01-basic-cleanup
	-- This cleans up journal.c such that the ugly 50+ character
	macro/derefs that are used repeatedly are evaluated once and
	then accessed using a temporary variable. The resulting code
	should be identical and makes it quite a bit nicer to read.

* cleanup-01-sb-opts
	-- This eliminates individual #defines for superblock/mount
	options and instead uses an enum. It's not like the actual
	values of the mount options matter, and this just makes a list
	of them. Accordingly, since the values aren't apparently in the
	include, I added a BUG_ON to bail out of the value passes beyond
	the size of the mount_opts variable.

* cleanup-02-bh-bits
	-- This patch makes all the accesses for bh->b_state use the
	appropriate macros, rather than accessing them directly.

* cleanup-03-bh-cleanup
	-- This patch eliminates the local macro implementation for the
	bh->b_state accessors/mutators and uses the FNS_BUFFER
	implementation in fs.h, which automatically creates the macros
	with on line of code.

* cleanup-04-sb-journal-elimination
	-- This patch is similar to the basic-cleanup, except that it
	focuses on the use of SB_JOURNAL(super) everywhere, and replaces
	it with a local "journal" variable. Again, this makes the code
	much easier to look at.

Opinions? Comments?

I apologize if this posted twice. The first message had the patches
attached, and crossed the post size limit. I haven't received a bounce yet.
