Adds the new zsmalloc library to the staging Kconfig and Makefile Signed-off-by:

Nitin Gupta authored
This patch creates a new memory allocation library named zsmalloc. NOTE: zsmalloc currently depends on SPARSEMEM for the MAX_PHYSMEM_BITS value needed to determine the format of the object handle. There may be a better way to do this. Feedback is welcome. Signed-off-by:

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. Signed-off-by:

Enable build of ramster as a staging driver Signed-off-by:

Dan Magenheimer authored
New files for ramster support: The file ramster.h declares externs and some pampd bitfield manipulation. The file zcache.h declares some zcache functions that now must be accessed from the ramster glue code. The file ramster_o2net.c is the glue between zcache and the o2net messaging code, providing routines called from zcache that initiate messages, and routines that handle messages by calling zcache. TODO explains future plans for merging. Signed-off-by:

In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle incoming data resulting from an async get) routines combine with a handful of changes to existing pamops interfaces allow the generic tmem code to support asynchronous operations. Also, a new tmem_xhandle struct groups together key information that must be passed to remote tmem stores. Zcache-main.c is augmented with a large amount of ramster-specific code to handle remote operations and "foreign" pages on both ends of the "remotify" protocol. New "foreign" pools are auto-created on demand. A "selfshrinker" thread periodically repatriates remote persistent pages when local memory conditions allow. For certain operations, a queue is necessary to guarantee strict ordering as out-of-order puts/flushes can cause strange race conditions. Pampd pointers now either point to local memory OR describe a remote page; to allow the same 64-bits to describe either, the LSB is used to differentiate. Some acrobatics must be performed to ensure local memory is available to handle a remote persistent get, or deal with the data directly anyway if the malloc failed. Lots of ramster-specific statistics are available via sysfs. Note: Some debug ifdefs left in for now. Signed-off-by:

Ramster-specific changes to ocfs2 cluster foundation, including: A method for fooling the o2 heartbeat into starting without an ocfs2 filesystem; a new message mechanism ("data magic") for handling a reply to a message requesting data; a hack for keeping the cluster alive even after timeouts so cluster machines can be rebooted separately.

Copy files from drivers/staging/zcache. Ramster compresses pages locally before transmitting them to another node, so we can leverage the zcache and tmem code directly. Note: there are no ramster-specific changes yet to these files. (Why copy? The ramster tmem.c/tmem.h changes are definitely shareable between zcache and ramster; the eventual destination for tmem.c is the linux lib directory. Ramster changes to zcache are more substantial and zcache is currently undergoing some significant unrelated changes (including a new allocator and breaking zcache-main.c into smaller files), so it seemed best to branch temporarily and merge later.)

Copy cluster subdirectory from ocfs2. These files implement the basic cluster discovery, mapping, heartbeat / keepalive, and messaging ("o2net") that ramster requires for internode communication. Note: there are NO ramster-specific changes yet; this commit does NOT pass checkpatch since the copied source files do not. (Why copy? This particular part of ocfs2 has never been broken out for non-ocfs2 use before, some (small) changes are required for ramster to use that code, and ramster is currently incompatible with real ocfs2 anyway (requires !CONFIG_OCFS2_FS). Before ramster can be promoted out of staging, we will need to work with the ocfs2 maintainers to see if the code interdependencies can be merged, but for now, for staging, this seemed to be an expedient way to make use of the ocfs2 core cluster code while still incorporating necessary changes for ramster.)
