Revision 6326fec1122cde256bd2a8c63f2606e08e44ce1d authored by Nicholas Piggin on 25 December 2016, 03:00:29 UTC, committed by Linus Torvalds on 25 December 2016, 19:54:48 UTC 
mm: Use owner_priv bit for PageSwapCache, valid when PageSwapBacked
 
A page is not added to the swap cache without being swap backed,
