commit fc676b00a7545743429e0c9b12a0f0707b1059aa
Author: Zbigniew Jędrzejewski-Szmek <zbyszek at in.waw.pl>

    core: do not add "what" to RequiresMountsFor for network mounts
    
    For cifs mount like //server/share, we would get
    RequiresMountsFor=/server/share, which probably isn't
    harmful, but quite confusing.
    
    Unfortunately a bunch of static functions had to be moved
    up, but patch is really one line.
