sys/kern : uipc_socket2.c
sys/sys : socketvar.h
Log message:
Bring back the SB_LOCK and SB_WANT flags to lock the socket buffers
in process context. The read/write lock introduced in rev 1.64
would create lock ordering problems with the upcoming SOCKET_LOCK()
mechanism. The current tsleep() in sblock() must be replaced with
rwsleep(&socketlock) later. The sb_flags are protected by
KERNEL_LOCK(). They must not be accessed from interrupt context,
but nowadays softnet() is not an interrupt anyway.
OK mpi@
