Subject[GIT PULL] xfs: more fixes for 4.17-rc4
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.

--D

The following changes since commit 7b38460dc8e4eafba06c78f8e37099d3b34d473c:

xfs: don't fail when converting shortform attr to long form during ATTR_REPLACE (2018-04-17 19:10:15 -0700)

are available in the Git repository at:

----------------------------------------------------------------
Changes since last update:
- Cap the maximum length of a deduplication request at MAX_RW_COUNT/2
to avoid kernel livelock due to excessively large IO requests.
