static

Coalesces the io fops with same fid and intent (read/write). A list of coalesced io segments is generated which is attached to a single io fop - res_fop (which is already bound to a session) in form of one of more network buffers and rest of the io fops hang off a list m0_rpc_item::ri_compound_items in resultant fop. The index vector array from io fop is also populated from the list of coalesced io segments. The res_fop contents are backed up and restored on receiving reply so that upper layer is transparent of these operations.
