commit: de5b8e8e047534aac6bc9803f96e7257436aef9c From: NeilBrown <[email protected]> Date: Tue, 7 Feb 2012 15:35:42 +1100 Subject: lockd: fix arg parsing for grace_period and timeout.
If you try to set grace_period or timeout via a module parameter to lockd, and do this on a big-endian machine where sizeof(int) != sizeof(unsigned long) it won't work. This number given will be effectively shifted right by the difference in those two sizes. So cast kp->arg properly to get correct result.
