This is complete overkill in printk.c. The only change required to
printk is to add a routine which gets the parameters that define the
buffer, see below from KDB. The rest of the code in your patch belongs
in the debugger, not in printk.

/* kdb dmesg command needs access to the syslog buffer. do_syslog() uses locks
* so it cannot be used during debugging. Just tell kdb where the start and
* end of the physical and logical logs are. This is equivalent to do_syslog(3).
void kdb_syslog_data(char *syslog_data[4])
syslog_data[0] = log_buf;
syslog_data[1] = log_buf + log_buf_len;
syslog_data[2] = log_buf + log_end - (logged_chars < log_buf_len ? logged_chars : log_buf_len);
syslog_data[3] = log_buf + log_end;
#endif /* CONFIG_KDB */
