Subject: [PATCH] powerpc: 64bit sendfile is capped at 2GB
Date: Wed, 4 Jun 2014 10:48:48 +1000 [thread overview]
Message-ID: <20140604104848.33275ace@kryten> (raw)
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.
