[GIT PULL] xfs, iomap: fixes for 4.8-rc3

[Dave Chinner]

Hi Linus,

Can you please pull the fixes from the tag list below? This update
contains fixes for most of the outstanding regressions introduced
with the 4.8-rc1 XFS and iomap infrastructure merge.

The only regression that isn't addressed by this pullreq is the aim7
write regression.  I'm still testing Christophs patches that address
the simple cases we've reproduced, but the cause of the aim7
regression is still not clear so there's more work to be done there.
Still, that's no reason to hold up all the other issues we have
tested fixes for.

Thanks!

-Dave.
