Replacing the use of kernel_thread() with kthread_run(). But as
kthread_run() returned a task structure, as compared with
kernel_thread() returning a PID, it was found to be more efficient to
store the task structure pointer as a field data instead of PID
pointer. On top of modifying the field to store task structure
pointer, the initialization of the field (assigned to
THREAD_PID_INIT_VALUE) was also found unnecessary - as no where it is
found to be used.
The patch (to be applied against linus git tree
v2.6.29-rc8-241-g65c2449) attached compiled and loaded successfully -
but not with the hardware, as I don't have it.
Thanks.
PS: attached passed checkpatch.pl. Thanks.
