Subject: Rename PG_checked to PG_owner_priv_1
From: Nick Piggin <nickpiggin@xxxxxxxxxxxx>
Rename PG_checked to PG_owner_priv_1 to reflect its availablilty as a
private flag for use by the owner/allocator of the page. In the case of
pagecache pages (which might be considered to be owned by the mm),
filesystems may use the flag.
