I've tested the patch, the Badness is gone and the system is stable as ever. Will this be pushed to 2.6.35?

Will this be pushed to 2.6.35? Hopefully yes :) Looks like Ben has deferred it to Grant in patchwork, and he is pretty busy I think with other OF patches ATM. Maybe he'll grab it or Ben can pick it up .. guys ? :) http://patchwork.ozlabs.org/patch/52978/ cheers > > fs/proc/proc_devtree.c | 3 +++ > > 1 files changed, 3 insertions(+), 0 deletions(-) > > > > diff --git a/fs/proc/proc_devtree.c b/fs/proc/proc_devtree.c > > index ce94801..d9396a4 100644 > > --- a/fs/proc/proc_devtree.c > > +++ b/fs/proc/proc_devtree.c > > @@ -209,6 +209,9 @@ void proc_device_tree_add_node(struct device_node *np, > > for (pp = np->properties; pp != NULL; pp = pp->next) { > > p = pp->name; > > > > + if (strchr(p, '/')) > > + continue; > > + > > if (duplicate_name(de, p)) > > p = fixup_name(np, de, p); > > > > -- > > 1.7.0.4 > > > > > > >

Some bogus firmwares include properties with "/" in their name. This causes problems when creating the /proc/device-tree file system, because the slash is taken to indicate a directory. We don't care about those properties, and we don't want to encourage them, so just throw them away when creating /proc/device-tree.
