Revision fc3501d411d34823fb9be248a95a0c44f945866f authored by Sven Wegener on 11 February 2009, 21:04:23 UTC, committed by Linus Torvalds on 11 February 2009, 22:25:35 UTC
We need to pass an unsigned long as the minimum, because it gets casted to an unsigned long in the sysctl handler. If we pass an int, we'll access four more bytes on 64bit arches, resulting in a random minimum value.
