    Subject[PATCH 0/3] use do_mount() instead of ksys_mount()
    Date
    This small series replaces all in-kernel calls to the
    userspace-focused wrapper ksys_mount() with calls to
    the kernel-centric do_mount().

    For each replacement, one needs to verify that the first and
    third parameter (char *dev_name, char *type) are strings
    allocated in kernelspace and that the fifth parameter
    (void *data) is either NULL or refers to a full page (only
    occurence in init/do_mounts.c::do_mount_root()). The second
    and fourth parameters (char *dir_name, unsigned long flags)
    are passed by ksys_mount() to do_mount() unchanged, and
    therefore do not require particular care.

    @viro: is this something for you to take and push upstream
    for the next cycle?
