[Samba] SETGID not being inherited

[Paul Worrall]

smbfs doesn't work at all for me :-( The share appears to be mounted but when 
I try to 'ls' it I get "Input/output error", and at the same time, log.smbd 
on the server records:

[2007/11/29 21:41:41, 0] lib/util.c:smb_panic(1599)
  PANIC (pid 5779): push_ascii - dest_len == -1

... followed by some backtrace info.

But that's a different problem.  To return to cifs: I found this on the 
linux-cifs-client mailing list archives:

http://marc.info/?l=linux-cifs-client&m=119027947932259&w=2

...which suggests that the clearing of the setgid bit is a known problem and 
it may be fixed in kernel 2.6.24.  Here's hoping!
