Ever since the block layer expanded its command syntax beyond just

2020-02-07T09:22:08Z

BIO_READ and BIO_WRITE, we've handled this expanded syntax poorly in drivers when the driver doesn't support a particular command. Do a sweep and fix that. Reported by: imp

Extract eventfilter declarations to sys/_eventfilter.h

2019-05-20T00:38:23Z

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Remove references to EISA support in mlx. The driver never supported

2017-02-16T21:56:32Z

the EISA cards and EISA bus support is being removed.

sys/dev: minor spelling fixes.

2016-05-03T03:41:25Z

Most affect comments, very few have user-visible effects.

sys/dev: extend use of the howmany() macro when available.

2016-04-26T15:03:15Z

We have a howmany() macro in the header that is convenient to re-use as it makes things easier to read.

sys/dev: use our nitems() macro when it is avaliable through param.h.

2016-04-19T23:37:24Z

No functional change, only trivial cases are done in this sweep, Drivers that can get further enhancements will be done independently. Discussed in: freebsd-current

Remove MAXBSIZE use from drivers where it has nothing to do.

2015-03-22T16:10:28Z

In some cases limits are just not needed, in others -- DFLTPHYS is the right constant to use instead. MFC after: 1 month
