    vfs: Convert ramfs, shmem, tmpfs, devtmpfs, rootfs to use the new mount API · f3235626
    David Howells authored
    Convert the ramfs, shmem, tmpfs, devtmpfs and rootfs filesystems to the new
    internal mount API as the old one will be obsoleted and removed.  This
    allows greater flexibility in communication of mount parameters between
    userspace, the VFS and the filesystem.
    
    See Documentation/filesystems/mount_api.txt for more information.
    
    Note that tmpfs is slightly tricky as it can contain embedded commas, so it
    can't be trivially split up using strsep() to break on commas in
    generic_parse_monolithic().  Instead, tmpfs has to supply its own generic
    parser.
    
    However, if tmpfs changes, then devtmpfs and rootfs, which are wrappers
    around tmpfs or ramfs, must change too - and thus so must ramfs, so these
    had to be converted also.
