Linux Kernel 4.18 Delayed: Bug Ate My rc7, Says Linus Torvalds


Linux kernel supremo Linus Torvalds has taken the rare step of reverting a kernel release candidate – after it went sour.

All looked sunny enough on Sunday evening, when he set Linux 4.18-rc7 free to roam: “Unless something odd happens, this should be the last rc for 4.18,” the chief penguinista wrote.
