[HPDD-discuss] [PATCH 2/3 v2] staging: lustre: ptlrpc: nrs_fifo: Replace OBD_CPT_ALLOC etc by kzalloc_node

Replace OBD_CPT_ALLOC, OBD_CPT_ALLOC_PTR, and OBD_CPT_ALLOC_GFP by corresponding calls to kzalloc_node. The semantic patch for the OBD_CPT_ALLOC case is as follows: (http://coccinelle.lip6.fr/). // <smpl> @@ expression ptr,cptab,cpt,size; @@ - OBD_CPT_ALLOC(ptr, cptab, cpt, size) + ptr = kzalloc_node(size, GFP_NOFS, cfs_cpt_spread_node(cptab, cpt)) // </smpl> Note that the original OBD macros would check if the cptab argument was NULL and fall back on kzalloc in that case. Oleg Drokin argues that this test is not needed because the code containing these calls is only invoked after initialization has been completed, in which case the possible cptab arguments are not NULL.
