    mm: fix KPF_SWAPCACHE in /proc/kpageflags · b6789123
    Hugh Dickins authored
    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.
