Dang!  That''s a real pain.  Sorry, but I can''t recommend an
alternative.

Applied the kernel patch which removed the static definition of sock_alloc.
Lustre seems to work fine now, using Openibnal.=20

Hi,=20
=20
I got Lustre 1.4.5 to build against 2.6.12.2 kernel + OpenIB 1.8.0. Everything
seems to work fine when I use ksocknal.=20
I had to make couple of changes to the openibnal layer (attached) to build
Lustre. Please let me know if the changes are ok and does not violate any
semantics. When I use kopenibnal and try to load llite, I get the following
error  in syslog:=20
=20
=20
Sep 23 23:46:26 n04 kernel: kopenibnal: Unknown symbol sock_alloc=20
=20
Googling seem to indicate sock_alloc has become static in 2.6.10. The site below
cites a patch to fix this.
https://www.redhat.com/archives/linux-cluster/2004-December/msg00169.html=20
=20
Any recommendations on alternative functions (instead of sock_alloc) to use in
openibnal  ? This saves the time of recompiling the kernel + associated
modules.=20
=20
