Nick Piggin 90dbb77ba4 fs: fix dropping of rcu-walk from force_reval_path ... As J. R. Okajima noted, force_reval_path passes in the same dentry to d_revalidate as the one in the nameidata structure (other callers pass in a child), so the locking breaks. This can oops with a chrooted nfs mount, for example. Similarly there can be other problems with revalidating a dentry which is already in nameidata of the path walk.
