2020-05-07scripts/gdb: repair rb_first() and rb_last()Aymeric Agon-Rambosson1-2/+2
The current implementations of the rb_first() and rb_last() gdb functions have a variable that references itself in its instanciation, which causes the function to throw an error if a specific condition on the argument is met. The original author rather intended to reference the argument and made a typo. Referring the argument instead makes the function work as intended.

2019-05-14scripts/gdb: add rb tree iterating utilitiesStephen Boyd1-0/+177
Implement gdb functions for rb_first(), rb_last(), rb_next(), and rb_prev(). These can be useful to iterate through the kernel's red-black trees.
