| |
while doing kernel-janitor msleep conversion of drivers own (incorrect), functions, some places would need msleep_interruptible().
this function is equivalent to: current->state = TASK_INTERRUPTIBLE; schedule_timeout(timeout);
idea from Ingo Molnar: well, aboves is not 100% equivalent because msleep() is uninterruptible so stoppage of the md thread (upon shutdown) will occur with only a 250 msec delay. Someone should add a msleep_interruptible() function to kernel/timer.c.
