Cover letter [patch 0/9] buffered write deadlock fix

The following set of patches attempt to fix the buffered write locking problems (and there are a couple of peripheral patches and cleanups there too).

Patches against 2.6.20-rc6. I was hoping that 2.6.20-rc6-mm2 would be an easier diff with the fsaio patches gone, but the readahead rewrite clashes badly :(

Please apply?

Thanks,
Nick
