Subject: mm/page_owner: fix %pGp format specifier argument type
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=781b0e74748f14b0e732eb736370bbbed181fe4d;p=thirdparty%2Flinux.git

mm/page_owner: fix %pGp format specifier argument type

The %pGp format specifier expects an argument of type 'unsigned long *',
but page->flags is now of type 'memdesc_flags_t' (a struct containing an
unsigned long member 'f') after the introduction of memdesc_flags_t.

Fix the type mismatch by passing &page->flags.f instead of &page->flags,
which matches the expected type.
