Subject: mm/mempolicy: Use vma_lookup() in __access_remote_vm()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=38d861132201fdde18d7fb91b0ea224902bdc03d;p=users%2Fjedix%2Flinux-maple.git

mm/mempolicy: Use vma_lookup() in __access_remote_vm()

vma_lookup() finds the vma of a specific address with a cleaner
interface and is more readable.
