Since the last August ;-) Bitmaps handling is a separate story (it got
less testing) but with the ->gfp_mask in tree it will be much simpler.
I'll port these patches to current tree if anyone is interested - all
infrastructure is already there, so it's only code in fs/ext2/* is touched.

Guys, help with testing directories-in-pagecache patch. It works fine
here and I would really like it to get serious beating.
Patch is on ftp.math.psu.edu/pub/viro/ext2-dir-patch-b-S2.gz (against
2.4.2, but applies to 2.4.3-pre* too).

(Linus, if you want me to mail it to you - just tell; comments on the
style would be _very_ welcome)

lseek() is per-file, so ->i_sem seems to be strange... I really don't see
why do we want a blocking semaphore there - spinlock (heck, even global
spinlock) should be OK, AFAICS. All we really want is atomic assignment
for 64bit and atomic += for the same beast.
Cheers,
Al
