RapidDisk is an advanced Linux RAM Disk which consists of a collection of modules and an administration tool. Features include: Dynamically allocate RAM as block device. Use them as stand alone disk drives or even map them as caching nodes to slower local disk drives.
I just tagged release version 7.2.1 on GitHub. It is a decent sized release. The changelog notes the following:
- module: Added support for RHEL 8.4 kernel
- utility: Added support for libmicrohttpd v0.9.71 and newer while still supporting legacy versions
