Lo
Neil, do you have a verdict on this patch?

I'm planning to apply the attached patch to hide the ARC-related data
structures in freelist.c. There are no data structure or algorithm
changes, just removal of ARC details from the shared header
buf_internals.h, plus minor refactoring to hide the knowledge that ARC
wants a twice-normal-size buff

Applied to HEAD with a few trivial editorial fixes.
Thanks for the patch.
Attached are two different variants of a patch to remove the ARC
cache algorithm in favor of variants of the "2Q" algorithm.
The first patch approximates the "full 2Q" algorithm described by
Johnson and Shasha, while the second approximates their "simplified 2Q"
method. Full 2Q uses a list of pag

Hello everyone.
I fixed two bugs in the patch that I sent before.
Check and test new one, please.
1. Fix update timing of Write->curridx. (pointed by Tom)
Change to update it soon after write().
2. Fix buffer alignment routine on 64bit cpu. (pointed by Mark)
I checked it on Xeon EM64T
