Shutemov Date: Thu, 14 Nov 2013 22:31:20 +0000 (-0800) Subject: mm: allow pgtable_page_ctor() to fail X-Git-Tag: upstream/snapshot3+hdmi~3973^2~54 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=390f44e2aa2ab83f08231d7d05f066dc3494490e;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git mm: allow pgtable_page_ctor() to fail Change pgtable_page_ctor() return type from void to bool. Returns true, if initialization is successful and false otherwise. Current implementation never fails, but it will change later. Signed-off-by: Kirill A.
