Hi
I am experienced embedded Linux driver developer. I have some spare
time which I want to contribute to mainstream Linux kernel.
Unfortunately http://kernelnewbies.org/KernelJanitors/Todo is very old.
Can you please suggest small tasks good for start? It can be code
clean up, API updates.

I guessed when u called select() it will
you might extend the "clean:" target to *really* clean the generated
artifacts in that directory. or perhaps introduce "distclean:".

Hi...
yup, less noise:
sudo ./ldt-test
stty: /dev/ttyS0: Input/output error
No loopback on /dev/ttyS0 detected, running ld
I've made test script less noise. Please update sources. The driver
and the the test works with UART too.

Yes, it is because you have no serial port. In this case LDT emulates loopback.

Let me share my thoughts from what I have read elsewhere (same concepts
below applies to many other OS like Solaris too, where a lot of the memory
concepts comes from) - in general understanding the principles so that u
will not get lost in the codes...which can be buggy as well:

Hi,
I have to capture kernel udev events through libudev. One of API
provides asynchronous events by reading on file descriptor. I found
that there two ways to do that.
1) select call
2) epoll
I also found that epoll is smarter and meant to replace old select call.
What are your thoughts on the

Hi
I develop template of Linux driver. It can be used as sample for Linux
driver development beginners and starting point for development of new
drivers.
The driver uses following Linux facilities: module, platform driver,
file operations (read/write, mmap, ioctl, blocking and non-blocking
mode,
