From: Andrew Morton Date: Tue, 12 Nov 2013 23:07:09 +0000 (-0800) Subject: mm/readahead.c:do_readhead(): don't check for ->readpage X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=63d0f0a3c7e1281fd79268a8d988167eff607fb6;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git mm/readahead.c:do_readhead(): don't check for ->readpage The callee force_page_cache_readahead() already does this and unlike do_readahead(), force_page_cache_readahead() remembers to check for ->readpages() as well.
