From: Randy Dunlap <rdunlap@infradead.org>
Fix sizeof argument to be the same as the data variable name. Probably a copy/paste error. Mostly harmless since both variables are unsigned int.
Fixes kernel bugzilla #197371: Possible access to unintended variable in "kernel/sysctl.c" line 1339 https://bugzilla.kernel.org/show_bug.cgi?id=197371
