The first VFS series of this cycle: ro-bind patches. FWIW,
I'm not particulary happy with the state of commit messages - practically
all changesets ended up with contributions from at least 2-3 people
(usually Dave/me/Christoph) and commit messages have too many [foo: fixed
bug in bar() noticed by baz] in them. OTOH, it's bisectable and hopefully
each changeset makes sense, which is one hell of a good reason to fold
fixes into affected changesets, IMO...
Anyway, please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ ro-bind.b6
