Samba on shares with XFS and kernel 2.6.18

[Stefan Gohmann]

Hello,

I've upgraded samba from Samba 3.3.9 to Samba 3.5.4. With Samba 3.5.4 and 
kernel 2.6.18 I can't upload files to a share on a XFS filesystem. With 
kernel 2.6.26 or 2.6.30 everything works fine.

* Samba 3.5.4 + Kernel 2.6.18
root at samba-38-2:~# uname -a

root at samba-38-2:~# smbclient -U Administrator \\\\samba-38-2\\Administrator
Enter Administrator's password: 
Domain=[SAMBATEST] OS=[Unix] Server=[Samba 3.5.4]
smb: \> put x.txt

putting file x.txt as \x.txt (1,0 kb/s) (average 1,0 kb/s)

Are older kernel versions no longer supported by newer samba versions? 

Cheers
Stefan
