The patch below contains the following possible cleanups for the current
infiniband code:
- make needlessly global code static
- don't build the completely unused core/fmr_pool.c
- #if 0 the following EXPORT_SYMBOL'ed but unused functions:
- core/device.c: ib_modify_device
- core/device.c: ib_modify_port
- core/mad.c: ib_coalesce_recv_mad
- core/mad.c: ib_process_mad_wc
- core/mad.c: ib_redirect_mad_qp
- core/mad.c: ib_register_mad_snoop
- core/ud_header.c: ib_ud_header_unpack
- core/verbs.c: ib_alloc_mw
- core/verbs.c: ib_dealloc_mw
- core/verbs.c: ib_modify_ah
- core/verbs.c: ib_query_ah
- core/verbs.c: ib_query_mr
- core/verbs.c: ib_query_qp
- core/verbs.c: ib_reg_phys_mr
- core/verbs.c: ib_rereg_phys_mr
- core/verbs.c: ib_resize_cq
- hw/mthca/mthca_cmd.c: mthca_QUERY_QP
If code will be added that uses some of the functions this patch
#if 0's it will be trivial to remove the corresponding #if 0's, but as
long as this hasn't happened, they only make the kernel needlessly
larger for people who use infiniband.
