Hi,
recently I got a report of a crash at pty_unix98_shutdown. after analyzing the
issue, I managed to create a small reproducer:
$ cat test.sh
#!/bin/sh
while true; do
find /sys
./dopty
echo 2 > /proc/sys/vm/drop_caches
ps aux
sleep 40
done
$ cat dopty.c
pty_unix98_shutdown allows a potential use after free of inode from
slave tty->driver_data: if final pty close is called with slave
tty_struct, and inode was released already by devpts_pty_kill at
pty_close, pty_unix98_shutdown will access stale data. If the evicted
inode is quickly reused again as

Now support CSV output for metrics. With the new output callbacks
this is relatively straight forward by creating new callbacks.

From: Andi Kleen
Enable metrics printing in --per-core / --per-socket mode. We need
to save the shadow metrics in a unique place. Always use the first
CPU in the aggregation. Then use the same CPU to retrieve the
shadow value later.

Abstract the printing of shadow metrics. Instead of every
metric calling fprintf directly and taking care of indentation,
use two call backs: one to print metrics and another to
start a new line.
This will allow adding metrics to CSV mode and also
using them for other purposes.

trip_point_temp_store() updates trip temperature. It should call
thermal_zone_device_update() immediately.

This patch enables to use thermal-zone on r8a7791.
This thermal sensor can measure temperature from -4 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver

This patch enables to use thermal-zone on DT if it was call as
"renesas,rcar-thermal-gen2".
Previous style is still supported by "renesas,rcar-thermal".

Every rcar_thermal_update_temp() return value will be checked.
And also, rcar_thermal_get_temp() always call

Current rcar thermal driver sometimes checks irq possibility when it
calls rcar_thermal_irq_enable/disable(), but sometimes not.
This patch checks it inside rcar_thermal_irq_enable/disable().

Hi
These are v5 of thermal-zone support for r8a7790/r8a7791.
Kuninori Morimoto (8):
1) thermal: rcar: move rcar_thermal_dt_ids to upside
2) thermal: rcar: check every rcar_thermal_update_temp() return value
3) thermal: rcar: check irq possibility in rcar_thermal_irq_xxx()

Hi Chao,
I also got superblock failure.
It seems that your patch doesn't handle correctly if segment0_blkaddr is not
zero.
Please see below.
