I'm looking into an issue with LTP's ustat01 & ustat02 tests in which
they report the following:
ustat01 1 FAIL : ustat(2) failed and setthe errno to 116 :
Stale NFS file handle
ustat02 2 FAIL : ustat(2) failed to produce expected error;
14, errno: EFAULT and got 116
It appears sometime between 2.6.21 and 2.6.22-rc1 some changes to NFS
got introduced that cause this.
was wondering about any ideas while I try to debug what's going on.
thanks

I'm seeing zero problems with the latest checkouts from Linus' git
tree.
Mind giving us some more details?
I tried 2.6.24-rc1 w/the same result.
The system is a 32-bit PPC embedded board that we mounting the rootfs
over nfs on.
The defconfig is arch/powerpc/configs/mpc8641_hpcn_defconfig
'strace' output would be useful, as would the standard NFS list of
client mount options, server export options, details on how your
exported partition is set up on the server, etc...
strace:
stat64("/", {st_dev=makedev(0, 14), st_ino=58821800, st_mode=S_IFDIR|
0775, st_nlink=18, st_uid=500, st_gid=500, st_blksize=4096,
st_blocks=8, st_size=4096, st_atime=2007/10/23-22:43:30,
st_mtime=2007/10/18-19:51:19, st_ctime=2007/10/18-19:51:19}) = 0
ustat(0xe, 0x1001a008) = -1 ESTALE (Stale NFS file
handle)
fstat64(1, {st_dev=makedev(0, 14), st_ino=58821964, st_mode=S_IFCHR|
