New Revision: 284594
URL: https://svnweb.freebsd.org/changeset/base/284594
Log:
Restore the td_cookie value for the tmpfs directory entry which was a
dup entry, upon detach from the parent directory. If the node is
renamed, the entry is re-attached at the different directory, and
invalud cookie value triggers assert (or corrupts directory rb tree,
it seems).
