__set_page_dirty_buffers() is calling __mark_inode_dirty under
mapping->private_lock.

We don't need to hold ->private_lock across that call.  It's only there
to pin page->buffers.

This simplifies the VM locking heirarchy.

When I converted ext3 to use to use direct-to-BIO writeback for
data=writeback mode I forgot that we need to hold a transaction open on
behalf of MAP_SHARED pages.  The fileystem is BUGging in get_block()
because there is no transaction open.

So let's forget that idea for now and send data=writeback mode back to
ext3_writepage.

it is an ex-parrot

assorted compile fixes

mtdblock switched to use of gendisks + compile fixes

z2ram.c switched to use of gendisks

ataflop.c switched to use of gendisks

amiflop.c switched to use of gendisks

macroectomy a-la pf.c and pcd.c ones, ditto for passing pointers to
structures instead of minors.

pd.c fed through Lindent

dumb expansion of macro - it had #define CURRENT current_req

tapeblock never assignes anything to its elements of blk_size[][]; we could
not bother allocating it in the first place.

More trivial fixes: typos in partitions/check.c, block/floppy.c and
acorn/block/fd1772.c + replacement of #define with inline in block/floppy.c
(fd_eject()).

Some trivial fixes for some typos introduced by Al's gendisk changes..

 - missing comma in cdu31a
 - missing semicolon in cdu31a
 - comma instead of colon in gscd
 - semicolon instead of comma in mcd
 - missing closing bracket in sonycd535

From Andries.

From davem: replace `unsigned' with size_t.

floppies and CD's in /proc/partitions.

Some idiot (OK, it was me) broke free_area_init_node for
non discontigmem systems that call it directly (eg sparc64),
during a recent cleanup, thus invoking the wrath of DaveM.

I know Dave sent you a patch yesterday, but I think the BUG
statement in it will break anyone who just uses free_area_init
(eg any PC). So here's a portion of Dave's patch that should
fix things for everyone I think. Unfortunately my non-NUMA
test box is borked right now, but it just removes the BUG
statement from what he tested, and it's so simple that even
I couldn't screw this up (famous last words).

This code really needs some more cleanup work, but this will
fix it for now so everyone can do their work ...
