You can ran into problems using schedule_timeout() in a block device request
function under 2.4.
This can be demonstrated by starting some I/O intensive tasks to your block
device and running sync in another task. Eventually the block layer will
lock up.
This can be fixed by creating a kernel

Oh well in that case it ought to task its task to something other than
TASK_RUNNING...

Well, first the "timeout" call will return immediately. Next, when the
time out actually happens, if the task is not TASK_RUNN
Am I right ? against test8pre1
Also, is it a bug to not set TASK_{UN}INTERRUPTIBLE before doing a
schedule_timeout() ? What will happen ?
