Update of /cvsroot/ssic-linux/openssi/kernel/include/cluster/ssi/cfs
In directory sfp-cvsdas-3.v30.ch3.sourceforge.com:/tmp/cvs-serv12379/include/cluster/ssi/cfs

Modified Files:
      Tag: OPENSSI-FC
	cfs_fs.h cfs_xdr.h 
Log Message:
CFS_PROTO->write/read() avoid use of kmap pools. Remove contention when kmap pool limit is reached as the number of CFS threads grows.
- Pre-allocate pagevec during RPC setup only if the pages are not already physically mapped.
- Reduce default CFS_SERVER rsize/wsize from 1MB to 64KB.
