commit: 1631fcea8399da5e80a80084b3b8c5bfd99d21e7 From: Chris Metcalf <[email protected]> Date: Mon, 26 Mar 2012 16:26:12 -0400 Subject: compat: use sys_sendfile64() implementation for sendfile syscall
<asm-generic/unistd.h> was set up to use sys_sendfile() for the 32-bit compat API instead of sys_sendfile64(), but in fact the right thing to do is to use sys_sendfile64() in all cases. The 32-bit sendfile64() API in glibc uses the sendfile64 syscall, so it has to be capable of doing full 64-bit operations. But the sys_sendfile() kernel implementation has a MAX_NON_LFS test in it which explicitly limits the offset to 2^32. So, we need to use the sys_sendfile64() implementation in the kernel for this case.
