The PVFS2-1.3.1 kernel module as shipped does not work with SLES 9,
since the SLES 9 headers bring in internal-only symbols (mmgrab and on
some platforms flush_icache_range).
The attached patch introduces a new configure option:
--disable-kernel-aio
This option should create a working pvfs2.ko kernel module on SLES9.
Let me know if it does not do the trick.
