From 57fc4a5ee322cde96c33f101d3c2d3b79011c05c Mon Sep 17 00:00:00 2001 From: Andrea Arcangeli Date: Tue, 1 Feb 2011 15:52:32 -0800 Subject: mm: when migrate_pages returns 0, all pages must have been released In some cases migrate_pages could return zero while still leaving a few pages in the pagelist (and some caller wouldn't notice it has to call putback_lru_pages after commit cf608ac19c9 ("mm: compaction: fix COMPACTPAGEFAILED counting")). Add one missing putback_lru_pages not added by commit cf608ac19c95 ("mm: compaction: fix COMPACTPAGEFAILED counting").
