From: Anton Blanchard Date: Wed, 4 Jun 2014 00:48:48 +0000 (+1000) Subject: powerpc: 64bit sendfile is capped at 2GB X-Git-Tag: firefly_0821_release~3679^2~1920 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1af791c05a5d17a5fdc086db3d9de7482ce358b0;p=firefly-linux-kernel-4.4.55.git powerpc: 64bit sendfile is capped at 2GB commit 5d73320a96fcce80286f1447864c481b5f0b96fa upstream. commit 8f9c0119d7ba (compat: fs: Generic compat_sys_sendfile implementation) changed the PowerPC 64bit sendfile call from sys_sendile64 to sys_sendfile. Unfortunately this broke sendfile of lengths greater than 2G because sys_sendfile caps at MAX_NON_LFS. Restore what we had previously which fixes the bug.
