[PATCH 0/7] Squashfs: performance enhancement patches

[Phillip Lougher]

Hi,

This is the latest version of the performance improvement
patches.

Patch 3/7 is a V2 of the percpu patch following review.

If there are no further review comments/objections I
intend to get these merged.

Any objections, then please object now.

Thanks

Phillip
