Hi Trond et al.,
I can reliably reproduce this oops on my diskless with NFS_ALL applied,
but not with plain-pre4, just by quitting one of {StarOffice,VMware}.

Haven't used any funky nfs options:

CONFIG_NFS_V3=y
# CONFIG_NFS_DIRECTIO is not set
CONFIG_ROOT_NFS=y
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
# CONFIG_NFSD_TCP is not set
CONFIG_SUNRPC=y
CONFIG_LOCKD=y
CONFIG_LOCKD_V4=y
It is not related to the symlink fix, I reverted it, just to be sure.
After reverting NFS_ALL, oopsing went away. Any ideas other then trying
all patches one by one :-(
Cheers,

The new version should be rid of it. It was a call to get_file() which
was missing a test for a NULL argument.

Would you mind to number up your NFS_ALL patch versions?

I forgot the nfs_cred_file() in the line above. That too is fixed now,
and so fsx is running fine again...

Would you like to give me a pointer to the famous fsx?
Just for the record, your actual NFS_ALL patch finally solved the problem(s),
it introduced ;-)
Many thanks.
