From 9c620e2bc5aa4256c102ada34e6c76204ed5898b Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Fri, 22 Feb 2013 16:35:14 -0800 Subject: mm: remove offlining arg to migrate_pages No functional change, but the only purpose of the offlining argument to migrate_pages() etc, was to ensure that __unmap_and_move() could migrate a KSM page for memory hotremove (which took ksm_thread_mutex) but not for other callers. Now all cases are safe, remove the arg.
