table of contents

Version 5.15 of the Linux kernel has been available since the beginning of November 2021. It has many improvements in its luggage, from which software developers, Linux administrators and experienced users who are keen to experiment can all benefit.

Linux advisor:

For the release of the new kernel, we had summarized the most important innovations in a compact way. In this article, we shed light on the technical details of selected features and outline how you can try them out in the course of your own kernel compilation and when writing your own programs.

Under our microscope: the ksmbd ksmbd kernel SMB server, the new NTFS3 NTFS3 driver from Paragon and the NUMA memory architecture, for which new areas of responsibility are currently being developed in the course of code extensions. Finally, we take a quick look at the Data Access MONitor (DAMON) and the system call process_mrelease () for the controlled “freeing up” of memory resources.
