Linus Torvalds released Linux5.3-rc3, which is smaller than the previous week's release candidate.
Not in the past week in the network fixes, so the change was driven mainly fixes (GPU is the most obvious, but there are other things: RDMA, SCSI, Xen) with the usual arch updates (mostly ARM 64 and s390), then there are others, such as: tools header file to be re-synchronized with the main kernel headers.
But in fact there is not much change, but most of the changes are small.
Torvalds brief comments on the 5.3-rc3 change can be found in the mailing list found in.
If you are not familiar with the changes brought about by the Linux5.3, please refer to the Linux 5.3 Overview of properties.
