This is a note to let you know that I've just added the patch titled crypto: hisilicon/qm - re-enable communicate interrupt before notifying PF to the 6.0-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-hisilicon-qm-re-enable-communicate-interrupt-.patch and it can be found in the queue-6.0 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e090d7bd37b283db6f9f689604eabb9d216391db Author: Weili Qian <qianweili@xxxxxxxxxx> Date: Sat Sep 24 19:04:31 2022 +0800 crypto: hisilicon/qm - re-enable communicate interrupt before notifying PF [ Upstream commit ee1537fe3dd89860d0336563891f6cac707d0cb5 ] After the device is reset, the VF needs to re-enable communication interrupt before the VF sends restart complete message to the PF. If the interrupt is re-enabled after the VF notifies the PF, the PF may fail to send messages to the VF after receiving VF's restart complete message.
