scripts/gdb: repair rb_first() and rb_last()

2020-05-27T15:46:36Z

[ Upstream commit 50e36be1fb9572b2e4f2753340bdce3116bf2ce7 ] 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.

scripts/gdb: add rb tree iterating utilities

2019-05-15T02:52:51Z

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.
