I don't think anyone has prepared a kzalloc() patch, but just adding
something like
static void *kzalloc(size_t size, unsigned int flags)
{
void *ret = kmalloc(size, flags);
if (ret)
memset(ret, 0, size);
return ret;
}
to files that use kzalloc() should let you use 2.6.13 (assuming there
are no other incompatibilities).
Thanks, that works.
Now, I have a problem with udapl :
The following is a code snippet from :
dapl_ib_dto.h
for (i = 0; i < segments; i++ ) {
if ( !local_iov[i].segment_length )
continue;
ds_array_p->addr = (uint64_t) local_iov[i].virtual_address;
ds_array_p->length = local_iov[i].segment_length;
ds_array_p->lkey = local_iov[i].lmr_context;
dapl_dbg_log ( DAPL_DBG_TYPE_EP,
" post_snd: lkey 0x%x va %p len %d \n",
ds_array_p->lkey, ds_array_p->addr,
ds_array_p->length );
total_len += ds_array_p->length;
wr.num_sge++;
ds_array_p++;
}
The following is the relevant part of the log with DAPL_DBG_TYPE=0xffff
dapl_ep_post_send (0x8087110, 2, 0x80f9910, %P, b5f395bc)^M
post_snd: ep 0x8087110 op 2 ck 0x8087374 sgs 2 l_iov 0x80f9910 r_iov
0xbfc29060 f 0^M
post_snd: ep 0x8087110 cookie 0x8087374 segs 2 l_iov 0x80f9910^M
post_snd: lkey 0x10de003b va 0xb5f3976c len 0 ^M
post_snd: lkey 0x10de003b va 0xb5f39924 len 0 ^M
^^^^^^^^
From the above loop, how is this possible :
If local_iov[i].segment_length == 0, it should not be printed. And the
if the assignment is successful, len must not be 0.
Any ideas? Of course following this, the ep is disconnected in the next
step :(
Also a minor patch, you can see that %P is printed as %P and not used as
a format character.
