 PDCP internals for  nr_pdcp_data_req_srb()/nr_pdcp_data_req_drb() are thread safe: inside them, the pdcp manager protects with the mutex the access to the SDU receiving function of PDCP (recv_sdu() callback, corresponding to nr_pdcp_entity_drb_am_recv_sdu() for DRBs). When it needs, the pdcp layer push this data to rlc by calling : rlc_data_req()

 At Rx side, pdcp_data_ind() is the entry point that receives the data from RLC.
 - Inside pdcp_data_ind(), the pdcp manager mutex protects the access to the PDU receiving function of PDCP (recv_pdu() callback corresponding to nr_pdcp_entity_drb_am_recv_pdu() for DRBs)
 - Then deliver_sdu_drb() function sends the received data to GTP thread through an ITTI message (GTPV1U_TUNNEL_DATA_REQ).
