[Lustre-discuss] Client Kernel panic - not syncing. Lustre 1.8.5

[Aaron Everett]

I'm getting a build error:
make[5]: Entering directory `/usr/src/kernels/2.6.18-238.9.1.el5-x86_64'
/usr/src/redhat/BUILD/lustre-1.8.5/lustre/mdc/mdc_lib.c:828: error:

mdc_internal.h:
     55 void mdc_getattr_pack(struct ptlrpc_request *req, int offset, __u64
valid,
     56                       int flags, struct mdc_op_data *data);

mdc_lib.c (patched version downloaded from link above):
    828 {
    829         if (mdc_req_is_2_0_server(req))
    830                 mdc_getattr_pack_20(req, offset, valid, flags, data,
ea_size);
    831         else
    832                 mdc_getattr_pack_18(req, offset, valid, flags,
data);
    833 }

Upon closer inspection, it appears this patch is for Lustre 1.8.6, while
we're running 1.8.5. Is there a download location for lustre source for
1.8.6? I don't see it on lustre.org.

Thanks again for your help!
Aaron
