When Linus Torvalds released
the 5.10 kernel, he noted that the 5.11 merge window would run up
against the holidays. He indicated strongly that maintainers should send
him pull requests early as a result. Maintainers appear to have listened;
over 10,000 non-merge changesets were pulled into the mainline in the first
three days of the 5.11 merge window. Read on for a summary of the most
significant changes in that flood of patches.
