The patch titled
Subject: mm/slab_common.c: use list_for_each_entry in dump_unreclaimable_slab()
has been removed from the -mm tree. Its filename was
mmslab_common-use-list_for_each_entry-in-dump_unreclaimable_slab.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Hui Su <sh_def@xxxxxxx>
Subject: mm/slab_common.c: use list_for_each_entry in dump_unreclaimable_slab()
dump_unreclaimable_slab() acquires the slab_mutex first, and it won't
remove any slab_caches list entry when itering the slab_caches lists.
Thus we do not need list_for_each_entry_safe here, which is against
removal of list entry.
