you can use "sys_mprotect" call which is kernel space equ. of "mprotect" .
The implementation for the same can be found in "mm\mprotect.c".

Is there some kernel api to validate memory allocated using kmalloc.
Suppose, I allocate some memory using kmalloc and at a later point of

I would like to validate if the memory allocated is not possibly freed by

Pls suggest a patch/pointers if any.
