Hello, I update currently a port of the FreeBSD network stack, etc. to the=20 real-time operating system RTEMS from the head version at 2017-04-04 to=20 the head version of today. I noticed that some read-write locks are=20 replaced by a relatively new stuff called EPOCH(9). Is there some=20 background information available for this? The man page is a bit vague=20 and searching for something named epoch on the internet is not really=20 great. For example, what is the motivation for this change? How is this=20 related to read-copy-update (RCU)? --=20 Sebastian Huber, embedded brains GmbH Address : Dornierstr. 4, D-82178 Puchheim, Germany Phone : +49 89 189 47 41-16 Fax : +49 89 189 47 41-09 E-Mail : sebastian.huber@embedded-brains.de PGP : Public key available on request.
