sysfs: Fix return values for sysdev_store_{ulong,int}

2008-10-29T22:03:49Z

SYSFS: Fix return values for sysdev_store_{ulong,int} Always return the full size instead of the consumed length of the string in sysdev_store_{ulong,int} This avoids EINVAL errors in some echo versions. Signed-off-by: Andi Kleen Cc: stable Signed-off-by: Greg Kroah-Hartman

driver core: drivers/base/sys.c: update comments

2008-10-29T22:03:49Z

There are no functions named sys_device_shutdown or sys_device_suspend in the kernel. They should be fixed to sysdev_shutdown and sysdev_suspend respectively. Signed-off-by: Qinghuang Feng Signed-off-by: Greg Kroah-Hartman

vmscan: unevictable LRU scan sysctl

2008-10-20T15:52:31Z

This patch adds a function to scan individual or all zones' unevictable lists and move any pages that have become evictable onto the respective zone's inactive list, where shrink_inactive_list() will deal with them. Adds sysctl to scan all nodes, and per node attributes to individual nodes' zones. Kosaki: If evictable page found in unevictable lru when write /proc/sys/vm/scan_unevictable_pages, print filename and file offset of these pages.

vmstat: mlocked pages statistics

2008-10-20T15:52:31Z

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.

vmscan: split LRU lists into anon & file sets

2008-10-20T15:50:25Z

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.
