[PATCHv2 00/11] Get rid of PG_reclaim and rename PG_dropbehind

[Kirill A. Shutemov]

Use PG_dropbehind instead of PG_reclaim and remove PG_reclaim.

After removing PG_relcaim, PG_readahead is exclusive user of the page
flag bit.

Once PG_reclaim is gone, we can rename PG_dropbehind to PG_reclaim.

Kirill A. Shutemov (11):
