sys/modules: normalize .CURDIR-relative paths to SRCTOP This simplifies make output/logic Tested with: `cd sys/modules; make ALL_MODULES=` on amd64 MFC after: 1 month Sponsored by: Dell EMC Isilon 2017-03-04 05:10:17 -05:00			`SYSDIR?= ${SRCTOP}/sys`
Use SYSDIR to reference to the top of the sys hierarchy. Define SYSDIR relative to .CURDIR if not already defined. This makes the makefiles more readable but also more re-usable and adaptable. Obtained from: Juniper Networks, Inc. 2014-03-05 20:59:13 -05:00

- For kernel compiled only with KDTRACE_HOOKS and not any lock debugging option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0]. [0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while. Fix this by using a protection stub, leaving sfxge driver authors the responsibility for fixing it appropriately [1].

Merge OpenZFS support in to HEAD. The primary benefit is maintaining a completely shared code base with the community allowing FreeBSD to receive new features sooner and with less effort. I would advise against doing 'zpool upgrade' or creating indispensable pools using new features until this change has had a month+ to soak. Work on merging FreeBSD support in to what was at the time "ZFS on Linux" began in August 2018. I first publicly proposed transitioning FreeBSD to (new) OpenZFS on December 18th, 2018. FreeBSD support in OpenZFS was finally completed in December 2019. A CFT for downstreaming OpenZFS support in to FreeBSD was first issued on July 8th. All issues that were reported have been addressed or, for a couple of less critical matters there are pull requests in progress with OpenZFS. iXsystems has tested and dogfooded extensively internally. The TrueNAS 12 release is based on OpenZFS with some additional features that have not yet made it upstream. Improvements include: project quotas, encrypted datasets, allocation classes, vectorized raidz, vectorized checksums, various command line improvements, zstd compression. Thanks to those who have helped along the way: Ryan Moeller, Allan Jude, Zack Welch, and many others. Sponsored by: iXsystems, Inc.
