Hi! There is a warning here:
net/ipv4/tcp_input.c:2959:6: warning: variable 'fast_rexmit' set but not used [-Wunused-but-set-variable]
2959 | int fast_rexmit = 0, flag = *ack_flag;
| ^
and another one in patch 2:
net/ipv4/tcp_input.c:3367:29: warning: variable ‘delta’ set but not used [-Wunused-but-set-variable]
3367 | int delta;
| ^~~~~
