Hi,
the recent discussion on the BKL made me check whether the BKL
really leads to bad locking. Most uses of BKL in drivers/usb/core
are in usbfs.
I am afraid the guy claiming that was not totally removed from
reality.
- devio.c::usbdev_open
Here we have an open with no protection at all against reentrancy.
The comment is absolutely bogus as open can sleep. Very bad.
Regards
Oliver
