[PATCH] sched/fair: Fix ksmd and kthreadd running on isolated CPU0 on arm64 systems

by wujing

This bug can be reproduced on Kunpeng arm64 and Phytium arm physical machines, as well as in virtual machine environments, based on the linux-4.19.y stable branch: 1. Check the number of CPUs on the system: nproc --all 96 2. Add the parameter isolcpus=0-85 to the grub configuration, update grub, and reboot. 3. Check the ksmd process: ps aux | grep -i ksmd root 502 0.0 0.0 0 0 ? S 10:00 0:00 [ksmd] ps -o pid,psr,comm -p 502 PID PSR COMMAND 502 0 ksmd 4.

S 10:00 0:00 [kthreadd] ps -o pid,psr,comm -p 2 PID PSR COMMAND 2 0 kthreadd From the output above, it can be seen that both ksmd and kthreadd are still running on CPU0, which is unreasonable since CPU0 has been isolated.

[PATCH v2] [ARM] fix reference leak in locomo_init_one_child()

by Ma Ke

Once device_register() failed, we should call put_device() to decrement reference count for cleanup. Or it could cause memory leak. device_register() includes device_add(). As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH] usb: chipidea: ci_hdrc_imx: decrement device's refcount on the error path of .probe()
