vmscan: change shrinker API by passing shrink_control struct

2011-05-25T15:39:26Z

Change each shrinker's API by consolidating the existing parameters into shrink_control struct. This will simplify any further features added w/o touching each file of shrinker.

staging: zcache: host services and PAM services

2011-02-09T23:07:13Z

[PATCH V2 2/3] drivers/staging: zcache: host services and PAM services Zcache provides host services (memory allocation) for tmem, a "shim" to interface cleancache and frontswap to tmem, and two different page-addressable memory implemenations using lzo1x compression. The first, "compression buddies" ("zbud") compresses pairs of pages and supplies a shrinker interface that allows entire pages to be reclaimed. The second is a shim to xvMalloc which is more space-efficient but less receptive to page reclamation. The first is used for ephemeral pools and the second for persistent pools. All ephemeral pools share the same memory, that is, even pages from different pools can share the same page. Signed-off-by: Dan Magenheimer Signed-off-by: Nitin Gupta Signed-off-by: Greg Kroah-Hartman
