The patch titled Subject: mm,vmacache: count number of system-wide flushes has been removed from the -mm tree. Its filename was mmvmacache-count-number-of-system-wide-flushes.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Davidlohr Bueso <dave@xxxxxxxxxxxx> Subject: mm,vmacache: count number of system-wide flushes These flushes deal with sequence number overflows, such as for long lived threads. These are rare, but interesting from a debugging PoV. As such, display the number of flushes when vmacache debugging is enabled.
