[PATCH v2 0/2] Implement word-at-a-time string functions for ARM

[Will Deacon]

Hi all,

This is version 2 of the patches originally posted here:

  http://lists.infradead.org/pipermail/linux-arm-kernel/2012-June/103290.html

There are only cosmetic changes from v1:
	- Added Nico's reviewed-by tags
	- Removed RFC prefix
	- Fixed changelog to echo the fact that we may use clz

I'm still interested in any pathname-heavy benchmarks that people may
have to stress the name hashing code. My simple find test does show an
improvement but I don't know how realistic that is.

Cheers,

Will
