I think, you don't need that (obj_num + 1) as because
rte_xmem_calc_int() will be checking flags for
_ALIGNED + _CAPA_PHYS_CONFIG i.e..
mask = MEMPOOL_F_CAPA_BLK_ALIGNED_OBJECTS | MEMPOOL_F_CAPA_PHYS_CONTIG;
if ((flags & mask) == mask)
/* alignment need one additional object */
elt_num += 1;
ok, You are removing above check in v2- 06/17, so ignore above comment.
I suggest to move this patch and keep it after 06/17. Or perhaps keep
common mempool changes first then followed by driver specifics changes in your
Finally I've decided to include these changes into the patch which
removes get_capabilities . Please, take a look at suggested version.
I think it is the most transparent solution. Otherwise it is hard
to avoid the issue found by you above.
I'm sorry, I've forgot to include you in CC.
