Subject: Fix: find_or_create_page skips cpuset memory spreading.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=43c0f3d25c602dc96b201ed81ffda0bc600ff969;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

Fix: find_or_create_page skips cpuset memory spreading.

We call alloc_page where we should be calling __page_cache_alloc.

__page_cache_alloc performs cpuset memory spreading.  alloc_page does not.
There is no reason that pages allocated via find_or_create should be
exempt.
