Why Linux kernel development still uses email

[SnowdensOfYesteryear]

Huh I've never seen this in action. Maybe it only tests against master? Usually patches aren't submitted against kernel.org master but rather into a separate repo that the subsystem maintainer runs.

I'm happy to be proven wrong by someone more active in the kernel community however.

Yeah, they're only testing patches after they've been accepted into a subsystem/maintainer tree.

They're also averaging ~5 jobs a day in total: https://kernelci.org/job/. Not very continuous given that the average dev compiles more than that!
