Coming one week after the third Release Candidate, Linux 4.11 RC4 appears to be just a bit smaller than the previous build, updating the networking stack and many of the supported drivers to be on par with what was changed earlier this week in the stable Linux kernel branches. Besides the usual driver updates and networking changes, the fourth Release Candidate of the Linux 4.11 kernel adds a bunch of core kernel improvements, an audit fix, a bpf hashmap fix, improvements to some of the supported hardware architectures, as well as to some of the filesystems.
