I started to review drivers for the new 2.4 SMP locking changes:
file_operations.{read,write,poll,readv,writev,fsync}
are called without lock_kernel().
I checked around 50 drivers, but
sg_poll()
is too complicated for an outsider. Could you double check that it can
run without the big kernel lock, or add lock_kernel calls?
TIA,
Manfred
