[PATCH] mm: msync() cleanup
With the tracking of dirty pages properly done now, msync doesn't need to scan
the PTEs anymore to determine the dirty status.
From: Hugh Dickins <hugh@veritas.com>
In looking to do that, I made some other tidyups: can remove several
#includes, and sys_msync loop termination not quite right.
Most of those points are criticisms of the existing sys_msync, not of your
patch. In particular, the loop termination errors were introduced in 2.6.17:
I did notice this shortly before it came out, but decided I was more likely to
get it wrong myself, and make matters worse if I tried to rush a last-minute
fix in. And it's not terribly likely to go wrong, nor disastrous if it does
go wrong (may miss reporting an unmapped area; may also fsync file of a
following vma).
