Is that an O_SYNC write, do you know?  Or a write to an inode
with the sync flag set?

I'm chasing down a problem similar to this atm, so far looks like
something in the generic VM code below sync_page_range is giving
back EAGAIN, and that is getting passed back out to userspace by
XFS.  Not sure where/why/how its been caused yet though ... I'll
let you know once I have a fix or have found the culprit change.

cheers.
