staging: zcache: delete it

2013-08-12T22:07:49Z

zcache is obsolete and not used anymore, Bob Liu has rewritten it and is submitting it for inclusion through the main -mm tree, as it should have been done in the first place... Cc: Bob Liu Cc: Konrad Rzeszutek Wilk Cc: Kyungmin Park Cc: Wanpeng Li Signed-off-by: Greg Kroah-Hartman

staging/zcache: Fix memory leak while dropping an o2net_sock_container object

2013-08-05T06:41:46Z

Free sc->sc_page when releasing a struct o2net_sock_container object to avoid memory leaks. This issue has been fixed by Younger Liu for OCFS2, so I sync that patch to zcache as we share the same network code base.

staging: zcache: enable ramster to be built/loaded as a module

2013-05-01T00:04:01Z

Enable module support for ramster. Note runtime dependency disallows loading if cleancache/frontswap lazy initialization patches are not present. If built-in (not built as a module), the original mechanism of enabling via a kernel boot parameter is retained, but this should be considered deprecated. Note that module unload is explicitly not yet supported.

Add incremental accessory counters that are going to be used for debug fs entries. Acked-by: Dan Magenheimer Signed-off-by: Wanpeng Li Signed-off-by: Greg Kroah-Hartman

staging: ramster/debug: Use an array to initialize/use debugfs attributes

2013-04-13T13:24:47Z

Use an array to initialize/use debugfs attributes, it makes them neater as zcache/debug.c does. Acked-by: Dan Magenheimer Signed-off-by: Wanpeng Li Signed-off-by: Greg Kroah-Hartman

staging: ramster: Move debugfs code out of ramster.c file

2013-04-13T13:23:33Z

Note that at this point there is no CONFIG_RAMSTER_DEBUG option in the Kconfig. So in effect all of the counters are nop until that option gets introduced in patch: ramster/debug: Add CONFIG_RAMSTER_DEBUG Kconfig entry Acked-by: Dan Magenheimer Signed-off-by: Wanpeng Li Signed-off-by: Greg Kroah-Hartman
