    fcntl(2):

    F_FREESP

    Free storage space associated with a section of the
    ordinary file fildes. The section is specified by a
    variable of data type struct flock pointed to by arg.
    The data type struct flock is defined in the
    header (see fcntl.h(3HEAD)) and is described below. Note
    that all file systems might not support all possible
    variations of F_FREESP arguments. In particular, many
    file systems allow space to be freed only at the end of
    a file.

    Konkretne treba ZFS tohle plne podporuje.
