kernel/sysctl.c: fix sizeof argument to match variable name
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 Link: http://lkml.kernel.org/r/e0d0531f-361e-ef5f-8499-32743ba907e1@infradead.org Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: Petru Mihancea <petrum@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
