Hello all, I am stuck up at invalidation of a page of a user level process. Wht i am doin is that i am calling a device driver ioctl func from a normal C prog in user space and passing a virtual address into the ioctl func .In the ioctl func (kernel space) i want to invalidate the corresponding page.I have used funcs like pte_clear, flush_tlb_page,page_remove_rmap,etc. but couldnt succeed.Also suggest if any locks have to be acquired .
Can anyone of u help me in page invalidation.I would be grateful. Thanking you in advance
