[git pull] vfs pile, part 2

From: Al Viro
Date: Fri May 28 2010 - 11:51:13 EST

Mostly assorted fixes + fsync API change + infrastructure and
simple conversions of "new truncate scheme" series. BTW, long-standing
abuse of file refcounting by aio.c is gone; now we have a new helper
(fput_atomic(file)) suitable for calling in atomic contexts. It drops
the reference if it's not the last one (i.e. if nothing potentially
blocking needs to be done) and tells the caller whether it had succeeded
or not (in the latter case you still need to do normal fput() outside of
atomic context, of course).

Please, pull from
