Iff mainline is not vulnerable, no problem but please communicate such a fact clearly. Also if your patch is not yet through your in-house QA, you can still send an "hey-i-have-an-idea..."-patch. Is the git repo listed in MAINTAINERS and the ocfs2 website still valid? It looks kinda outdated... git://git.kernel.org/pub/scm/linux/kernel/git/jlbec/ocfs2.git OCFS2 development seems to be very opaque currently. -- Thanks, //richard
