Commit 6326fec1 ("mm: Use owner_priv bit for PageSwapCache, valid when PageSwapBacked") aliased PG_swapcache to PG_owner_priv_1 (and depending on PageSwapBacked being true). As a result, the KPF_SWAPCACHE bit in '/proc/kpageflags' should now be synthesized, instead of being shown on unrelated pages which just happen to have PG_owner_priv_1 set. Signed-off-by:
