* Merge td_epochnest with td_no_sleeping.Gleb Smirnoff2019-10-291-1/+0
| | | | | | | | | | | | | | | | | | | Epoch itself doesn't rely on the counter and it is provided merely for sleeping subsystems to check it. - In functions that sleep use THREAD_CAN_SLEEP() to assert correctness. With EPOCH_TRACE compiled print epoch info. - _sleep() was a wrong place to put the assertion for epoch, right place is sleepq_add(), as there ways to call the latter bypassing _sleep(). - Do not increase td_no_sleeping in non-preemptible epochs. The critical section would trigger all possible safeguards, no sleeping counter is extraneous. Reviewed by: kib Notes: svn path=/head/; revision=354148

* make critical_{enter, exit} inlineMatt Macy2018-07-031-0/+44
Avoid pulling in all of the <sys/proc.h> dependencies by automatically generating a stripped down thread_lite exporting only the fields of interest. The field declarations are type checked against the original and the offsets of the generated result is automatically checked. kib has expressed disagreement and would have preferred to simply use genassym style offsets (which loses type check enforcement). jhb has expressed dislike of it due to header pollution and a duplicate structure. He would have preferred to just have defined thread in _thread.h. Nonetheless, he admits that this is the only viable solution at the moment. The impetus for this came from mjg's D15331: "Inline critical_enter/exit for amd64" Reviewed by: jeff Differential Revision: https://reviews.freebsd.org/D16078 Notes: svn path=/head/; revision=335879
