I believe the only problem with that is that sys_sched_setscheduler()
expects the struct sched_param pointer to reside in user-space memory.
Therefore, when do_sched_setscheduler calls copy_from_user() to trasnfer
the contents to a kernel-space structure, it will fail.

Hi All ,
I wanted to use a system call from kernel module to change
the priority of the process using sys_sched_setscheduler from kernel
space after using get_fs by modifying the |addr_limit| of the task to
KERNEL_DS using set_fs and get_fs apis.
I wanted to what will be the disadvantage in using the System Calls from
kernel space if it not any file system call.
Thanks and Regards,
John Endeavour
