    Linux: Flush vcaches when a mount fails
    GetVCache (well, really NewVCache) creates a new vcache, with an attached
    inode, and links it into the VLRU queue, regardless of whether it is
    successful in populating that vcache or not. The attached inode, on Linux,
    contains a reference to the super block of the filesystem. If the created
    vcache is for the root, however, and populating that vcache failes, then mount
    fails, and the super block is disposed of. This leaves us with a vcache in
    the VLRU queue which contains a reference to a non-existent inode.
    When ShakeLooseVCaches comes along a few minutes later, it attempts to discard
    this inode. However, doing so fails because the inode no longer has a valid
    super block.
    Avoid this trauma by ensuring all vcaches are disposed of before the super
    block goes away, in the event of a mount failure.
