Many thanks for your answer,

I used a 2.2.17 kernel that can be found on the net, but I don't know if
its name is Vanilla
I've patched it with the two patches i've found on sistina site for LVM
0.9

I did some other tests:
-  I wrote a small test C programm that use memset. I was able to
compile and execute it
without any problem.
-  Compiling the 2.2.17 kernel without LVM option and the patches works
fine.
-  I declared the memset function in lvm.c as  static (*memset)(void *,
int, size_t);
   and I was able to compile it, without any message saying that
reference to memset is not found !!

Unfortunately, I'm not familiar with C and I don't see what can be the
problem.

regards,
PhiL
