[linux-mm-cc] [ANNOUNCE] compcache-0.6pre1 release

[Nitin Gupta]

Hi All,

compcache-0.6pre1 is out! This brings some new features:
 - Support for _file_ as backing swap. Earlier we supported only block
device as backing swap.
 - Support for multiple ramzswap devices. Earlier there was only one
hardcoded device (/dev/ramzswap0).
(see Changelog for details).

These features will also help with scalability problem to some extent --
instead of creating one giant ramzswap
device, you can now create multiple such devices. Each device has separate
memory pool, compression buffers,
locking. Thus, contention for resources will be less with multiple devices.

Also, swap files are lot more flexible than swap partitions. So, it should
be useful to have in-memory compression
layer over swap files too.

These feature introduced a lot of new code and major code re-organization
(diff v.s. version 0.5.3 is ~3000 lines!).
So, it still needs lot of testing before final release.

README contains all the information needed to compile and use it. A new wiki
page has been created to
focus on this release:
http://code.google.com/p/compcache/wiki/CompilingAndUsingNew

Known bugs:
 - Issue 33 <http://code.google.com/p/compcache/issues/detail?id=33>: swapon
fails on android G1 (ARM)


Thanks,
Nitin
