reiserfs cleanup patchset

Hi all -

I've had this patchset kicking around for a while. After a conversation this past week about code that was horrible to read (using reiserfs's balance_leaf as the primary example) and seeing that Dave Jones had scratched a bit of an itch, I decided it was time to resync and push it out so I don't have to update it forever.

BTW, as I'm basically the only person with substantial patches against reiserfs, I'm 100% ok with disrupting context to this extent. :)

This set consists of 29 patches in a few areas.

1 - Convert the commit workqueue to a per-fs workqueue
2 - Clean up ugly accessor macros to use more readable names
3 - Clean up comments to use the normal kernel style
4 - Remove the unused nblocks argument from journal_end
5 - Remove superblock argument from journal_end (it's in the trans handle) 6 - Remove superblock argument from journal_mark_dirty (see #5) 7 - Remove blocks argument from journal_join (it's always 1)
8 - Remove leading whitespace from labels
9 - Remove unnecessary parents
10 - Clean up dirent creation
11 - Clean up hash detection
12-29 - Clean up balance_leaf - This 2500-line function goes through
6 easily distinguishable stages, each with several sub-parts. The patch set splits up the stages and then reformats them to keep the split as obvious as possible. The final result is a whole lot easier to follow and easier on the eyes.
