that write access to a member requires both locks and read access only requires one of the given locks. Convert instances of '(c+)' to '(c + k)' as a result. - Change p_pptr from (e) to (c + e). - Change p_oppid from (c) to (c + e). - Change p_args from (b?) to (c + k). - Move the actual work of STOPEVENT, PHOLD, and PRELE to _STOPEVENT, _PHOLD, and _PRELE. The new macros do not acquire the proc lock and simply assert that it is held. The non _ prefixed macros acquire the proc lock and then call the _ prefixed macros. - Add a PROC_LOCK_NOSWITCH() macro to be used when releasing the proc lock while already holding a spin lock (usually sched_lock). - Add a PROC_LOCK_ASSERT() macro to be used to make assertions about the proc lock. It takes the usual mtx_assert() macro arguments as its second argument.
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
