If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 7362042f3556528e9e9b1eb5ce8d7a3a6331476b Mon Sep 17 00:00:00 2001 From: Peng Liu <liupeng17@xxxxxxxxxx> Date: Tue, 21 Mar 2023 14:19:29 +0800 Subject: scripts/gdb: fix lx-timerlist for Python3 From: Peng Liu <liupeng17@xxxxxxxxxx> commit 7362042f3556528e9e9b1eb5ce8d7a3a6331476b upstream. Below incompatibilities between Python2 and Python3 made lx-timerlist fail to run under Python3. o xrange() is replaced by range() in Python3 o bytes and str are different types in Python3 o the return value of Inferior.read_memory() is memoryview object in Python3 akpm: cc stable so that older kernels are properly debuggable under newer Python.
