is it right with the following:

tasklets scheduled by a irq-handler may interrupt
1) the request fuction of a block device driver
2) a open/close system call of a block device driver

if i don't want to be interrupted by a tasklet i need
to call local_bh_disable or because (i've to use spin-
locks anyway) spin_lock_bh.
