[Xen-devel] [PATCH Linux 2.6.31] Add hugepage support to the balloon driver
This patch adds a boot command line switch "balloon_hugepages" that makes the balloon driver work entirely in hugepages. This version of the code checks to make sure each page is contiguous at the machine level. If it is not, it frees each page individually. When the huge page is reallocated it will be contiguous.

Does this depend on any other changes to support hugepages? Is "Dave McCracken <dcm@mccr.org>" the address you want to sign this off with, or an Oracle address?

It is part of the set of changes for hugepage support, but it works entirely independently of them.> Is "Dave McCracken <dcm@mccr.org>" the address you want to sign this off > with, or an Oracle address?Use "Dave McCracken <dave.mccracken@oracle.com>" . The other address is the one that''s subscribed to the mailing list so is the one I have to send from.

Will do. >Thanks. And you may as well write it up as a proper patch with the complete commit comment, s-o-b line and generate the diff so that it applies with "patch -p1" (ie, Linux convention).
