[PATCH] knfsd: nfsd: oops exporting nonexistent directory
Export a directory that does not exist:
exportfs -orw,fsid=0,insecure,no_subtree_check client:/home/NFS4
Try to mount from client with nfs4. Mount hangs (I'm not sure why -
that's another issue).
While client is hung, back on server
mkdir /home/NFS4
The server panics in dput. I traced the problem back to svc_export_parse()
calling path_release() even though path_lookup() failed (it happens to fill in
the nameidata structure with a negative dentry - so the test after out:
succeeds).
After patching, an recreating the problem, the client mount still takes some
time before finally exiting with a message "couldn't read superblock".
Here is a simple patch to resolve this issue:
