Since these are pretty serious bugs, and I try to avoid merging known-broken patches which will go up to Linus, why don't you go ahead and respin the patchset with the new fixes included. You can also use the opportunity to squash in the rename patch and fix that mid-patchset compilation problem that I fixed up during the merge. Thanks. -- paul moore www.paul-moore.com
