teach move_mount(2) to work with OPEN_TREE_CLONE
Allow a detached tree created by open_tree(..., OPEN_TREE_CLONE) to be
attached by move_mount(2).
If by the time of final fput() of OPEN_TREE_CLONE-opened file its tree is
not detached anymore, it won't be dissolved. move_mount(2) is adjusted
to handle detached source.
That gives us equivalents of mount --bind and mount --rbind.
Thanks also to Alan Jenkins <[email protected]> for
providing a whole bunch of ways to break things using this interface.
