    [XFS] use filldir internally · 051e7cd4
    Christoph Hellwig authored
    Currently xfs has a rather complicated internal scheme to allow for
    different directory formats in IRIX. This patch rips all code related to
    this out and pushes useage of the Linux filldir callback into the lowlevel
    directory code. This does not make the code any less portable because
    filldir can be used to create dirents of all possible variations
    (including the IRIX ones as proved by the IRIX binary emulation code under
    arch/mips/).
    
    This patch get rid of an unessecary copy in the readdir path, about 400
    lines of code and one of the last two users of the uio structure.
    
    This version is updated to deal with dmapi aswell which greatly simplifies
    the get_dirattrs code. The dmapi part has been tested using the
    get_dirattrs tools from the xfstest dmapi suite1 with various small and
    large directories.
