    exofs: fix pnfs_osd re-definitions in pre-pnfs trees · 89be5030
    Boaz Harrosh authored
    Some on disk exofs constants and types are defined in the pnfs_osd_xdr.h
    file. Since we needed these types before the pnfs-objects code was
    accepted to mainline we duplicated the minimal needed definitions into
    an exofs local header. The definitions where conditionally included
    depending on !CONFIG_PNFS defined. So if PNFS was present in the tree
    definitions are taken from there and if not they are defined locally.
    
    That was all good but, the CONFIG_PNFS is planed to be included upstream
    before the pnfs-objects is also included. (The first pnfs batch might be
    pnfs-files only)
    
    So condition exofs local definitions on the absence of pnfs_osd_xdr.h
    inclusion (__PNFS_OSD_XDR_H__ not defined). User code must make sure
    that in future pnfs_osd_xdr.h will be included before fs/exofs/pnfs.h,
    which happens to be so in current code.
    
    Once pnfs-objects hits mainline, exofs's local header will be removed.
