mlock: count attempts to free mlocked page

2008-10-20T15:52:31+00:00

Allow free of mlock()ed pages. This shouldn't happen, but during developement, it occasionally did. This patch allows us to survive that condition, while keeping the statistics and events correct for debug.

vmstat: mlocked pages statistics

2008-10-20T15:52:31+00:00

Add NR_MLOCK zone page state, which provides a (conservative) count of mlocked pages (actually, the number of mlocked pages moved off the LRU). Reworked by lts to fit in with the modified mlock page support in the Reclaim Scalability series.

unevictable lru: add event counting with statistics

2008-10-20T15:50:26+00:00

Fix to unevictable-lru-page-statistics.patch Add unevictable lru infrastructure vm events to the statistics patch. Rename the "NORECL_" and "noreclaim_" symbols and text strings to "UNEVICTABLE_" and "unevictable_", respectively. Currently, both the infrastructure and the mlocked pages event are added by a single patch later in the series. This makes it difficult to add or rework the incremental patches. The events actually "belong" with the stats, so pull them up to here. Also, restore the event counting to putback_lru_page(). This was removed from previous patch in series where it was "misplaced". The actual events weren't defined that early.

vmscan: split LRU lists into anon & file sets

2008-10-20T15:50:25+00:00

Split the LRU lists in two, one set for pages that are backed by real file systems ("file") and one for pages that are backed by memory and swap ("anon"). The latter includes tmpfs. The advantage of doing this is that the VM will not have to scan over lots of anonymous pages (which we generally do not want to swap out), just to find the page cache pages that it should evict. This patch has the infrastructure and a basic policy to balance how much we scan the anon lists and how much we scan the file lists. The big policy changes are in separate patches.

Subject: [PATCH] hugetlb: vmstat events for huge page allocations

2008-04-28T15:58:23+00:00

Allocating huge pages directly from the buddy allocator is not guaranteed to succeed. Success depends on several factors (such as the amount of physical memory available and the level of fragmentation). With the addition of dynamic hugetlb pool resizing, allocations can occur much more frequently. For these reasons it is desirable to keep track of huge page allocation successes and failures. Add two new vmstat entries to track huge page allocations that succeed and fail. The presence of the two entries is contingent upon CONFIG_HUGETLB_PAGE being enabled.
