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

2013-05-01T00:04:01+00:00

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.

[v1: Fixed compile issues since ramster_init now has four arguments]
[v2: Fixed rebase on ramster->zcache move]
[akpm@linux-foundation.org: use_frontswap_selfshrink cannot be __initdata]

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

2013-04-13T13:24:47+00:00

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

2013-04-13T13:23:33+00:00

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
