Subject[PATCH 0/3] zram: generic RAM based compressed R/W block devices
Date
Creates RAM based block devices: /dev/zramX (X = 0, 1, ...).
Pages written to these disks are compressed and stored in memory
itself. These disks allow very fast I/O and compression provides
good amounts of memory savings.

This is enhancement over existing ramzswap driver which creates
virtual block devices (/dev/ramzswapX) which could be used only
as swap disks.

Now, with the ability to handle any kind of I/O request, zram
devices have lot more use cases:
- /tmp storage
- various caches under /var
- swap disks
- maybe even more! :)

Performance numbers can be found at:
http://code.google.com/p/compcache/wiki/zramperf

Patch 1 makes core changes to support handling generic I/O
requests. Subsequent patches rename ramzswap* files to zram*
and similar changes in code and documentation.

Support generic I/O requests
Rename ramzswap to zram in code.
