It obtains the matching inode for a kernfs_node. It will be used by cgroup for inode based permission checks for now but is generally useful. Signed-off-by: Tejun Heo Cc: Greg Kroah-Hartman --- Hello, Greg. Given that cgroup will be the first and only, for now, user, I think it'd be the eaiest to route this with the related cgroup patches through the cgroup tree. What do you think?
