mm: page_owner: use kstrtobool() to parse bool option
I tried to use page_owner=1 for a while noticed too late it had no effect as opposed to similar init_on_alloc=1 (these work). Let's make them consistent. The change decreses binary size slightly: text data bss dec hex filename 12408 321 17 12746 31ca mm/page_owner.o.before 12320 321 17 12658 3172 mm/page_owner.o.after Link: https://lkml.kernel.org/r/20210401210909.3532086-1-slyfox@gentoo.org Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org> Reviewed-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
