Fix a regression caused by Commit 7fc34a62ca mm/msync.c: sync only
the requested range in msync().
xfstests generic/075 fail occured on ext4 data=journal mode because
the intended range was not syncing due to wrong fstart calculation.

Looks good to me and it fixes the issues with data=journal on ext4.

I can confirm that this patch corrects the ext4 regressions I reported on
3.16-rc1 for data_journal.
Additionally, it corrects regressions for two other tests I have not yet
reported. Those tests include generic/263 when running with the
data=journal mount option, and generic/219 (a quota test that doesn't use
fsx) when running with all xfstests-bld scenarios (4k, ext4, nojournal, 1k,
etc.) with the exception of bigalloc. The generic/219 failure on bigalloc in
3.16-rc1 is not a regression, and was present in earlier releases.
With this patch, ext4 3.16-rc3 regression results on x64_64 should look much
more like 3.15 final.
Thanks guys!
Eric

Andrew, do you want to take this in the mm tree, or shall I take it in
the ext4 tree? I would prefer if we could get this pushed to Linus as
soon as possible, since it fixes a regression.
