Hello!
Where could I find documentation, example about kernel module work and how use it?
For xfs and xdd there are example skeletons inside the source tree. Just look for the skeleton folders in freemint/sys/{xfs,xdd}
Does we can ask to not prempt process in critical part of the code in kernel module?
The kernel never preeempt itself except on explicit request by calling the scheduler.
