6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuan-Ying Lee <kuan-ying.lee@xxxxxxxxxxxxx>
commit a633a4b8001a7f2a12584f267a3280990d9ababa upstream.
Patch series "Fix some GDB command error and add some GDB commands", v3.
Fix some GDB command errors and add some useful GDB commands.
This patch (of 5):
Commit 7988e5ae2be7 ("tick: Split nohz and highres features from
nohz_mode") and commit 7988e5ae2be7 ("tick: Split nohz and highres
features from nohz_mode") move 'tick_stopped' and 'nohz_mode' to flags
field which will break the gdb lx-mounts command:
(gdb) lx-timerlist
Python Exception <class 'gdb.error'>: There is no member named nohz_mode.
Error occurred in Python: There is no member named nohz_mode.
(gdb) lx-timerlist
Python Exception <class 'gdb.error'>: There is no member named tick_stopped.
Error occurred in Python: There is no member named tick_stopped.
We move 'tick_stopped' and 'nohz_mode' to flags field instead.
