Zstd Compression Support Coming For Linux Pstore

Linux’s Pstore “persistent store” functionality, which is most often used for preserving kernel panics and related information across reboots when the system runs into a show-stopping problem, will soon be supporting Zstd compression for storing greater amounts of data.

Pstore is often backed by flash chips with limited capacities as their non-volatile storage for securing the last bits of system debugging details across reboots.
