Ubuntu 4.15.x kernel crash : net_sched: fix a race condition in tcindex_destroy()

[Viktor S. Wold Eide]

Dear list,

Sorry if this issue should have been raised elsewhere.

I am running into a kernel crash issue using latest Ubuntu 4.15 kernel. I
could not see that this fix has made it into the Ubuntu 4.15 kernel so far.

The kernel crash issue was fixed in February in the Linux kernel:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=056a17982adbd52b2a6c5ec6266cee4521cd931b

Will this fix get merged into the Ubuntu 4.15 kernels?

I did test one of the recent kernel-ppa/mainline kernels, more specifically:
linux-image-unsigned-4.19.34-041934-generic_4.19.34-041934.201904051741_amd64.deb
It seems to fix the problem, that is, no crashes experienced so far.

Best regards
Viktor S. Wold Eide
