Hi!

This patch has significantly changed locking scheme in
lookup functions. This was to solve race problems which
surfaced while testing on SMP system.

[Patch download]:
http://prdownloads.sourceforge.net/linuxcompressed/patch-ccache-alpha-007-2.6.18?download

I tested this patch on 32-bit system Only with 10M for
page-cache and 5M for swap-cache (RAM: 128M).

I think, porting compression algos. to 64-bit is all thats
needed for 64-bit ccache support. Please mail me
(or mailing list) if you are interested in this.

It will be great help if anyone can please provide
code review for this patch :)


* Changelog: ccache-alpha-007 (applies to 2.6.18)

Changes since ccahe-alpha-006
-- Major locking changes in lookup functions.
-- Fixed chunk_head usage count which could lead to 'double free'
-- Removed abt. 500 LOC.


Cheers,
Nitin
