I don't know why, maybe it's because of the list of new features that I link to later, but I have the feeling that the next version of the Linux kernel will be more important than anyone expects. In the past week was launched Linux 5.3-rc1 and was the largest version in size since Linux 4.9-rc1. This week have thrown Linux 5.3-rc2 and it is still very big, something that its creator, Linus Torvalds, expected after all the requests they had to attend to before the launch of the first Release Candidate of this version.
Torvalds does not mention many details about the changes he has made to release this version, other than that has made corrections for everything, without a pattern. From the looks of it, the size still had to be maintained in this second Release Candidate and it won't be until next week or the next when it starts to downsize (this is a personal opinion).
Linux 5.3-rc2: reasonably large
The corrections have been applied in architecture updates, drivers (gpu, iommu, networks, nvdimm, sound ...), kernel, network filter, file systems, etc. All very big, but Torvalds says that there is nothing I would highlight as too serious. What is certain is that the fact that he begins his email with a "hmmm" makes us think that he is pensive, that he is not totally calm, perhaps because he likes everything to be perfect.
Linux 5.3 will be officially launched in about two months. The next major release of the Linux kernel will arrive with many news, among which we have support for the mice and keyboards of the latest MacBook or initial support for Intel Speed Select technology in Cascadelake processors, but an incompatibility with the NVIDIA driver has also been introduced in the first versions in the Power architectures that have to fix before the official Linux 5.3 release. They are 7-8 weeks old, so I think we shouldn't worry.
