Kernel – 5.3-rc1 is Out. NVIDIA OK, VMware vmmon Fails, and a Fix. — 7 Comments

  1. That doesn’t seem right, force_sig() in v5.3-rc1 takes signal number as an argument. I believe the right call would be send_sig(SIGKILL, linuxState.fastClockThread, 1) – see e.g. kernel commit 1dfd1711de29. However, getting to this call should be rather rare so you might never find out if you pass something wrong. 🙂

  2. Problem with VirtualBox also.

  4. smp_call_function() return type was changed to void in 5.3-rc1 (commit caa759323c73) as it always returned 0 since 2.6.29-rc1 anyway. So simply drop the assignment and handling of non-zero rc (if there is some).
