This update fixes:
- incorrect warnings about i_mutex locking in
pagecache_isize_extended() and updates comments to match expected
locking
- another zero-range bug fix for stray file size updates
- a bunch of fixes for regression in the bulkstat code introduced in
3.17.

Pull xfs fixes from Dave Chinner:
"This update fixes a warning in the new pagecache_isize_extended() and
updates some related comments, another fix for zero-range
misbehaviour, and an unforntuately large set of fixes for regressions
in the bulkstat code.
The bulkstat fixes are large but necessary. I wouldn't normally push
such a rework for a -rcX update, but right now xfsdump can silently
create incomplete dumps on 3.17 and it's possible that even xfsrestore
won't notice that the dumps were incomplete. Hence we need to get
this update into 3.17-stable kernels ASAP.
In more detail, the refactoring work I committed in 3.17 has exposed a
major hole in our QA coverage. With both xfsdump (the major user of
bulkstat) and xfsrestore silently ignoring missing files in the
dump/restore process, incomplete dumps were going unnoticed if they
were being triggered. Many of the dump/restore filesets were so small
that they didn't evenhave a chance of triggering the loop iteration
bugs we introduced in 3.17, so we didn't exercise the code
sufficiently, either.
We have already taken steps to improve QA coverage in xfstests to
avoid this happening again, and I've done a lot of manual verification
of dump/restore on very large data sets (tens of millions of inodes)
of the past week to verify this patch set results in bulkstat behaving
the same way as it does on 3.16.
Unfortunately, the fixes are not exactly simple - in tracking down the
problem historic API warts were discovered (e.g xfsdump has been
working around a 20 year old bug in the bulkstat API for the past 10
years) and so that complicated the process of diagnosing and fixing
the problems. i.e. we had to fix bugs in the code as well as
discover and re-introduce the userspace visible API bugs that we
unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly.
Summary:
- incorrect warnings about i_mutex locking in pagecache_isize_extended()
and updates comments to match expected locking
- another zero-range bug fix for stray file size updates
- a bunch of fixes for regression in the bulkstat code introduced in
3.17"
