Re: Transparent Hugepage Support #29

[Ed Tomlinson <edt@aei.ca>]

Andrea,

I have been tracking & testing this for a while.   It looks very much like Linus wants to merge (or a big chunk of it):

git://git.kernel.org/pub/scm/linux/kernel/git/npiggin/linux-npiggin.git vfs-scale-working

When I pull an aa-29 on top of this there is one conflict in vmscan.c that git cannot resolve.
It would be really nice to have a version of the THS patchs that can be tested with the vfs scaling
tree.

TIA
Ed Tomlinson
