Subject: Merge branch 'vm-cleanups' (unmap_vma() interface cleanup)
X-Git-Tag: v3.5-rc1~195
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dddbd5414bee86d14bbc835163ca72e4e457c80a;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

Merge branch 'vm-cleanups' (unmap_vma() interface cleanup)

This series sanitizes the interface to unmap_vma().  The crazy interface
annoyed me no end when I was looking at unmap_single_vma(), which we can
spend quite a lot of time in (especially with loads that have a lot of
small fork/exec's: shell scripts etc).

Moving the nr_accounted calculations to where they belong at least
clarifies things a little.  I hope to come back to look at the
performance of this later, but if/when I get back to it I at least don't
have to see the crazy interfaces any more.

* vm-cleanups:
  vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces
  vm: simplify unmap_vmas() calling convention
