staging: zcache: fix Kconfig crypto dependency

2012-04-24T18:57:36+00:00

ZCACHE is a boolean in the Kconfig.  When selected, it
should require that CRYPTO be builtin (=y).

Currently, ZCACHE=y and CRYPTO=m is a valid configuration
when it should not be.

This patch changes the zcache Kconfig to enforce this
dependency.

staging: zcache: make zcache builtin only

2012-03-07T21:30:17+00:00

zcache cannot currently be loaded as a module.  However
the Kconfig allows it to be built as a module; something that
the user probably does not intend since the module is not
loadable.

This patch switches zcache from a tristate to a bool in the Kconfig

staging: fix powerpc linux-next break on zsmalloc

2012-02-13T14:57:17+00:00

linux/vmalloc.h added to zsmalloc-main.c to resolve implicit
declaration errors.

X86 dependency added to zsmalloc and dependent drivers zcache and zram.

This X86 only requirement is not ideal.  Working to find portable
functions for __flush_tlb_one and set_pte.

staging: zcache: crypto API support

2012-02-09T01:09:27+00:00

This patch allow zcache to use the crypto API for page compression.
It replaces the direct LZO compress/decompress calls with calls
into the crypto compression API. The compressor to be used is
specified in the kernel boot line with the zcache parameter like:
zcache=lzo or zcache=deflate.  If the specified compressor can't
be loaded, zcache uses lzo as the default compressor.

[PATCH V2 3/3] drivers/staging: zcache: misc build/config

Makefiles and Kconfigs to build zcache in drivers/staging

There is a dependency on xvmalloc.* which in 2.6.37 resides
in drivers/staging/zram.  Should this move or disappear,
some Makefile/Kconfig changes will be required.
