[coyotos-dev] Micro-monolithic linux kernel

[Sandro Magi]

Linux to get a userspace driver API to simplify driver development:

'This interface allows the ability to write the majority of a driver in
userspace with only a very small shell of a driver in the kernel itself.
It uses a char device and sysfs to interact with a userspace process to
process interrupts and control memory accesses.'

Seems they're hitting that monolithic complexity wall, and the lessons
of microkernels are becoming more appreciated.
