The region is left in the tree with dirty set and its\ncompletion never signalled. Later binds over that range then fail\npermanently -- -ENOENT or -EINVAL from the dirty checks, or an unkillable\nwait_for_completion() in bind_validate_region() -- for the lifetime of\nthe uvmm.\n\nClear reg->dirty when the unwind reverts the sparse unmap, restoring the\nregion to the state it was found in."
