Modified files:
sys/netinet tcp_subr.c
Log:
Introduce a new TCP mutex, isn_mtx, which protects the initial sequence
number state, rather than re-using pcbinfo. This introduces some
additional mutex operations during isn query, but avoids hitting the TCP
pcbinfo lock out of yet another frequently firing TCP timer.
