    mnt: Move the clear of MNT_LOCKED from copy_tree to it's callers. · 8486a788
    Eric W. Biederman 提交于
    Clear MNT_LOCKED in the callers of copy_tree except copy_mnt_ns, and
    collect_mounts.  In copy_mnt_ns it is necessary to create an exact
    copy of a mount tree, so not clearing MNT_LOCKED is important.
    Similarly collect_mounts is used to take a snapshot of the mount tree
    for audit logging purposes and auditing using a faithful copy of the
    tree is important.
    
    This becomes particularly significant when we start setting MNT_LOCKED
    on rootfs to prevent it from being unmounted.
