Hi all, file systems that write out of place usually require different alignment for direct I/O writes than what they can do for reads. This series tries to address this by yet another statx field. Note that the code is completely untested - I wrote it and got preempted and only sent this out because Hongbo Li brought the issue up in the nilfs2 context. I've just started a vacation so I'm unlikely to get back to it any time soon, but if someone wants to take the work over go for it. I'll probably answer to email at least every other day or so.
