regs_get_kernel_stack_nth() - get Nth entry of the stack : pt_regs which contains kernel stack pointer.
: stack entry number.
regs_get_kernel_stack_nth() returns
th entry of the kernel stack which is specified by . If the
th entry is NOT in the kernel stack, this returns 0.
regs_get_kernel_stack_nth() - get Nth entry of the stack :pt_regs which contains kernel stack pointer.
:stack entry number.
regs_get_kernel_stack_nth() returns
th entry of the kernel stack which is specifined by . If the
th entry is NOT in the kernel stack, this returns 0.
regs_query_register_name() - query register name from its offset : the offset of a register in struct pt_regs.
regs_query_register_name() returns the name of a register from its offset in struct pt_regs. If the is invalid, this returns NULL;
regs_within_kernel_stack() - check the address in the stack : pt_regs which contains kernel stack pointer. : address which is checked.
regs_within_kernel_stack() checks is within the kernel stack page(s). If is within the kernel stack, it returns true. If not, returns false.
