[Samba] Problem with smbfs on 2.4.18 kernel

Hi all..
I have found some problems on smbfs module in 2.4.18 kernel.
I compiled it by myself (not the very first kernel compilation in my life
;-)) and then I have got it. Looks like it touch smbfs module as when I
recompile 2.4.18 modules with smbfs sources changed to sources of smbfs
from 2.4.17 problem disappears!!
My mainboard is Abit BE6 with Pentium III 450 MHz. I am using SuSE 7.3 with
all available patches. Base kernel was 2.4.16 from SuSE update but I wanted
to change it now to 2.4.18. The same problem apperas in fact in 2.4.18
kernel distributed by Hubert Mantel from SuSE team. But as I realized it is
also in vanila - I am reporting it to main developers I hope.
Here are a lot of infos I could get during and after teh problem appears
(lucky taht system does not hangs totally ;-))
If anything else is needed please let me know. Hope it can help you to find
teh problem out.
Best regard
Marcin Gryszczuk.

Can not remove smbfs module
linux:~ # rmmod smbfs
smbfs: Device or resource busy
Then I have took all source files for ./fs/smbfs from 2.4.17 kernel and put
into 2.4.18 source tree and
I just made make modules (on first compiled 2.4.18 kernel that I have used
in previous test). SO only
smbfs.o was changed - and I put this new one into
/lib/modules/2.4.18/kernel/fs/smbfs directory
I reboot teh computer and I do teh same commands after start:
linux:~ # mount -t smbfs -o username=xxx,password=xxx //comp017/d$ /mnt

And now everything goes OK.
So it is definetely in smbfs !!
