If CONFIG_BPF_SYSCALL=y, but CONFIG_BPF_JIT=n:
net/smc/smc_hs_bpf.c: In function ‘bpf_smc_hs_ctrl_init’:
include/linux/bpf.h:2068:50: error: statement with no effect [-Werror=unused-value]
2068 | #define register_bpf_struct_ops(st_ops, type) ({ (void *)(st_ops); 0; })
| ^~~~~~~~~~~~~~~~
net/smc/smc_hs_bpf.c:139:16: note: in expansion of macro ‘register_bpf_struct_ops’
139 | return register_bpf_struct_ops(&bpf_smc_hs_ctrl_ops, smc_hs_ctrl);
| ^~~~~~~~~~~~~~~~~~~~~~~
While this compile error is caused by a bug in <linux/bpf.h>, none of
the code in net/smc/smc_hs_bpf.c becomes effective if CONFIG_BPF_JIT is
not enabled. Hence add a dependency on BPF_JIT.
While at it, add the missing newline at the end of the file.

SMC-R provides a "sockets over RDMA" solution making use of

RDMA over Converged Ethernet (RoCE) technology to upgrade
|

AF_INET TCP connections transparently.

The Linux implementation of the SMC-R solution is designed as

a separate socket family SMC.

SMC_HS_CTRL_BPF enables support to register generic eBPF hook for SMC
|
|
handshake flow, which offer much greater flexibility in modifying the behavior
|
|
of the SMC protocol stack compared to a complete kernel-based approach. Select
|
|
this option if you want filtring the handshake process via eBPF programs.
