Kernel 6.2 promises multiple filesystem improvements
The forthcoming Linux kernel 6.2 should see improved filesystem handling, including performance gains for SD cards and USB keys, as well as FUSE. As for the next-gen storage subsystems… not so much.
For a mature OS kernel, there are still considerable improvements being made in Linux's handling of existing disk formats, and this should improve when kernel 6.2 appears at some point in early 2023.
A patch from Sony engineer Yuezhang Mo makes it quicker to create new files or directories on an exFAT disk with lots of files on it – and the more files there are, the bigger the improvement. This follows the same programmer's earlier patch to improve exFAT handling, in March.
