The patch titled
Subject: mm, vmstats: new THP splitting event
has been removed from the -mm tree. Its filename was
mm-vmstats-new-thp-splitting-event.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>
Subject: mm, vmstats: new THP splitting event
The patch replaces THP_SPLIT with tree events: THP_SPLIT_PAGE,
THP_SPLIT_PAGE_FAILED and THP_SPLIT_PMD. It reflects the fact that we are
going to be able split PMD without the compound page and that
split_huge_page() can fail.
