epoch(9): Make epochs non-preemptible by default2018-05-18T17:29:43ZMatt Macymmacy@FreeBSD.org2018-05-18T17:29:43Zurn:sha1:70398c2f86e2fbc2120b4a11d9ec9284a6a395f5
There are risks associated with waiting on a preemptible epoch section.
Change the name to make them not be the default and document the issue
under CAVEATS.

epoch: add non-preemptible "critical" variant2018-05-18T01:52:51ZMatt Macymmacy@FreeBSD.org2018-05-18T01:52:51Zurn:sha1:5e68a3dfe30c07337bca284ea65cfe2c4b06d249
adds:
- epoch_enter_critical() - can be called inside a different epoch,
starts a section that will acquire any MTX_DEF mutexes or do
anything that might sleep.
- epoch_exit_critical() - corresponding exit call
- epoch_wait_critical() - wait variant that is guaranteed that any
threads in a section are running.
- epoch_global_critical - an epoch_wait_critical safe epoch instance

Test priority handling in epoch test.2018-05-11T04:47:05ZMatt Macymmacy@FreeBSD.org2018-05-11T04:47:05Zurn:sha1:ef7f29d8e6adac30c7125f8c185f22282155d926
- Double the number of test threads to mp_ncpu*2
- Give each thread a different scheduling priority
Add simple preempt safe epoch API2018-05-10T17:55:24ZMatt Macymmacy@FreeBSD.org2018-05-10T17:55:24Zurn:sha1:06bf2a6aefbf98f0717954368a8791cd70bfba30
Read locking is over used in the kernel to guarantee liveness. This API makes
it easy to provide livenes guarantees without atomics.
Includes epoch_test kernel module to stress test the API.
Documentation will follow initial use case.
Test case and improvements to preemption handling in response to discussion
