The patch titled Move page_assign_page_cgroup to VM_BUG_ON in free_hot_cold_page has been removed from the -mm tree. Its filename was memory-controller-memory-accounting-v7-move-page_assign_page_cgroup-to-vm_bug_on-in-free_hot_cold_page.patch This patch was dropped because it was folded into memory-controller-memory-accounting-v7.patch The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: Move page_assign_page_cgroup to VM_BUG_ON in free_hot_cold_page From: Balbir Singh <balbir@xxxxxxxxxxxxxxxxxx> Based on the recommendation and observations of Hugh Dickins, page_cgroup_assign_cgroup() is not required. This patch replaces it with a VM_BUG_ON, so that we can catch them in free_hot_cold_page() Signed-off-by: Balbir Singh <balbir@xxxxxxxxxxxxxxxxxx> Cc: Hugh Dickins <hugh@xxxxxxxxxxx> Signed-off-by:
