Client and Server on the same machine : Fedora Core6 (2.6.24-rc2-CITI_NFS4_ALL-1) on Intel(R) Xeon(TM) X86_64 CPU 2.80GHz bi-ways 64 bits

Testing Tool	NFSV4 sec=sys 2 hours
Simultaneously in loopback fsstress +fsx +iozone (no -U) +ffsb +cthon04-t (ext)	FAILED (1)

Remarks:
(1) All the applications suspended after around 2 hours. The hang is nevertheless different from this one got
with the 2.6.23-rc9-CITI_NFS4_ALL-1 where nfsd was looping using 100%cpu.See BUGZILLA #152

1) By default, rpcsec_gss_krb5 module needs to be loaded

2) Exports syntax for security flavors

RHEL5.1 supports gss/krb5, gss/krb5i, gss/krb5p syntax but not the sec=krb5p:krb5i:krb5:sys syntax

*When doing the following NFSV4 mount and umount sequence ,
*the first "umount" doesn't give error messages  even when we are under the
mounting point
*but the second umount tells well unmounting is not possible


mount /mnt/nosec
cd /mnt/nosec
umount /mnt/nosec

*No messages here telling unmounting not possible
*The commands "mount" tells /mnt/nosec is no longer mounted
*but /proc/mounts still contains the mount.
*If we do a second:

umount /mnt/nosec

*we get normally

umount: /mnt/nosec: device is busy

*By no longer being under the mounted directory

cd /
umount /mnt/nosec

*We effectively unmount

2) Exports syntax for security flavors

"gss/krb5, gss/krb5i, gss/krb5p" syntax and the new one "sec=krb5p:krb5i:krb5:sys" syntax are both supported
