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. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
