From
Subjectmy view about schedule( ) and system call , right or wrong ?
schedule( ) always runs in kernel space, therefore  the address of all
elements used by schedule() is not virtual address but physical
address.?


analogous question also appears in system call , when I define myself
syscall , for example:

asmlinkage long sys_check(a,b ,c){

unsigned long buf;

...........
}

then , the buf is stored in kernel space , that is , physical address .


right or wrong
