usbip: somtimes stalls at kernel_recvmsg()

[NÃmeth MÃrton]

Hi,

I'm working with usbip and I sometimes see a stall when I run
the "lsusb" command from the userspace. I added some debug messages
and it seems that the kernel_recvmsg() in
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/staging/usbip/usbip_common.c;h=210ef16bab8d271a52e5d36cd1994aad57ad99e1;hb=HEAD

This is the only place I could find where the TCP messages are arriving in
the usbip code.

What happens if a message does not arrive? Does it stall forever? If
yes, how can the kernel_recvmsg() call changed to handle some timeout?
