https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v3.82012-10-03T01:35:55Zcompat: fs: Generic compat_sys_sendfile implementation2012-10-03T01:35:55ZCatalin Marinascatalin.marinas@arm.com2012-09-19T11:01:52Zurn:sha1:8f9c0119d7ba94c3ad13876acc240d7f12b6d8e1
This function is used by sparc, powerpc and arm64 for compat support.
The patch adds a generic implementation which calls do_sendfile()
directly and avoids set_fs().
The sparc architecture has wrappers for the sign extensions while
powerpc relies on the compiler to do the this. The patch adds wrappers
for powerpc to handle the u32->int type conversion.
compat_sys_sendfile64() can be replaced by a sys_sendfile() call since
compat_loff_t has the same size as off_t on a 64-bit system.
On powerpc, the patch also changes the 64-bit sendfile call from
sys_sendile64 to sys_sendfile.

aio_read()/aio_write() methods.
