[PATCH v1 0/7] binderfs: debug galore

[Christian Brauner]

Hey everyone,

Al gave me a really helpful review of binderfs and pointed out a range
of bugs. The most obvious and serious ones have fortunately already been
taken care of by patches sitting in Greg's char-misc-linus tree. The
others are hopefully all covered in this patchset.

/* Changelog */
Nothing major apart from working in a bunch of good comments and
suggestions from Al. The most interesting one is probably the switch
from d_alloc_name() + d_lookup() to lookup_one_len() when detecting name
clashes between binder devices. This also forces us to switch from
d_add() to d_instantiate() since lookup_one_len() adds new dentries to
the hashqueue. If we were to use d_add() after this we'd end up with the
same dentry over the same inode twice. I moved the switch from d_add()
to d_instantiate() into a separate commit.
The rest should hopefully be pretty mundane.

Thanks!
Christian
