Subject: [PATCH 0/2] scsi: ufs: critical health condition

Martin hi,
The UFS4.1 standard, released on January 8 2025, is adding several new
features. Among them a new exception event: HEALTH_CRITICAL, which
notify the host of a device's critical health condition. This
notification implies that the device is approaching to the end of its
life time based on the amount of performed program/erase cycles.

We use the hw monitor subsystem to proliferate this info via the chip
alarm channel.

Please consider this for the next merge window.

Thanks,
Avri
