From 8bfe8d32bddc1b1f2c7f9eca4af4e13e72c76bad Mon Sep 17 00:00:00 2001 From: Anton Blanchard <anton@samba.org> Date: Wed, 4 Jun 2014 10:48:48 +1000 Subject: [PATCH Trusty SRU] UBUNTU: SAUCE: (no-up) powerpc: 64bit sendfile is capped at 2GB BugLink: http://bugs.launchpad.net/bugs/1328230 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.
