Hi Linus,
I've got one more bug fix for xfs for 4.17-rc4, which caps the amount of
data we try to handle in one dedupe request so that userspace can't
livelock the kernel.
This series has been run through a full xfstests run during the week and
through a quick xfstests run against this morning's master, with no ajor
failures reported. Let me know if there are any merge problems.

- Cap the maximum length of a deduplication request at MAX_RW_COUNT/2
