From: Petr Tesarik <ptesarik@xxxxxxx>
Subject: kexec: export PG_swapbacked to VMCOREINFO
Since commit 6326fec1122cd ("mm: Use owner_priv bit for PageSwapCache,
valid when PageSwapBacked"), PG_swapcache is an alias for PG_owner_priv_1,
which may be also used for other purposes. To know whether the bit indeed
has the PG_swapcache meaning, it is necessary to check PG_swapbacked,
hence this bit must be exported.
