Overview ¶
Package mountfd provides a "mount object" file descriptor, as returned by fsmount(2) or open_tree(2) with OPEN_TREE_CLONE.
A mount object fd can be used as an argument to move_mount(2) to place the mount on the directory tree, or it can be used as a dirfd argument to the *at() syscalls. If a mount object fd is closed without calling move_mount(2), the mount is unmounted.
