From: Linus Torvalds Date: Thu, 13 Aug 2009 15:28:36 +0000 (-0700) Subject: Make sock_sendpage() use kernel_sendpage() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e694958388c50148389b0e9b9e9e8945cf0f1b98;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Make sock_sendpage() use kernel_sendpage() kernel_sendpage() does the proper default case handling for when the socket doesn't have a native sendpage implementation. Now, arguably this might be something that we could instead solve by just specifying that all protocols should do it themselves at the protocol level, but we really only care about the common protocols. Does anybody really care about sendpage on something like Appletalk? Not likely. Acked-by: David S.
