This issue is probably the regression caused by the removal of an ifdef
when the VFS removed the generic_file_fcntl call.
The experimental cifs directory notify code was enabled around 2.6.8 or
2.6.9 (should have been disabled) which is fixed in current mainline
(2.6.10-rc) bk tree and in mm (and also the cifs dnotify code has been
fixed to not hang in these cases). The q;uick way to fix this is to
remove the refrence to the cifs notify routine in the two file operations
lists in fs/cifs/cifsfs.c (or wait for 2.6.10).
We really need a good dnotify test case (smaller than running kde and with
easier to undertand behavior and error code display) so we can catch it if
someone breaks notify and so I can finish testing of notify (Samba's code
looks not quite right either as I test the experimental code against
Windows and Samba servers).
