Note that volunary context switches value for
16901 [cifsd] increased between the two dumps, so I suspect that the
routines in the top of the stacktrace are repeated.

According to what the man page of |proc| says,
> 11: 0400A8C0:B6B4 7000A8C0:01BD 01 00000079:00000000 01:00001580

This is for the CIFS mount.
7000A8C0:01BD -> 112.0.168.192 (reverse of 192.168.0.112 the address of
Win7 host) : 445 (port # of CIFS tcp mount)

I hope this might give a clue.
