Hi all,
Since the big usb-serial semaphore has been gone for the usb-serial
drivers for a while now in 2.5, I've been trying to audit all of the
drivers to make sure that they are still SMP safe. I think I've either
fixed up, or validated that there are no problems in the following
drivers:
belkin_sa.c
digi_acceleport.c
empeg.c
ir-usb.c
kl5kusb105.c
mct_u232.c
omninet.c
pl2303.c
safe_serial.c
visor.c
I'll still work on the following drivers:
io_edgeport.c
io_ti.c
keyspan.c
keyspan_pda.c
But that still leaves a number of drivers left. If the
owners/maintainers of the following drivers can check to make sure their
locking is safe, I would really appreciate it:
cyberjack.c
ftdi_sio.c
ipaq.c
kobil_sct.c
whiteheat.c
The last one, whiteheat.c does look like it has locking, but it's wrong,
and will spit out nasty messages to the kernel log when you run it with
CONFIG_DEBUG_SPINLOCK_SLEEP enabled.
Thanks,
greg k-h
