Linux 7.3 UBI introduces per-device wear-leveling thresholds for NAND flash management

The UBI layer in the Linux kernel, which handles NAND flash memory tracking and wear leveling, now supports configurable wear-leveling thresholds on a per-device basis.
Previously, wear-leveling thresholds appear to have been a global setting rather than tunable per device, which limited operators' ability to optimize flash lifetime across mixed NAND hardware. Per-device thresholds let engineers tune wear-leveling behavior to match the characteristics of individual flash chips. Only one feed reported this and no article body was available, so implementation details are limited.

The UBI (Unsorted Block Images) layer in the Linux kernel manages NAND flash memory tracking and wear leveling.
Linux 7.3 UBI adds the ability to set wear-leveling thresholds on a per-device basis rather than as a single global value.
Only one source reported this change and no article text was available, so details on configuration interface and behavior are absent.
