Mark Johnston 33cb9b3c3a graid3: Fix teardown races Port commit `dc399583ba` from g_mirror, which has an effectively identical startup sequence. This fixes a race that was occasionally causing panics during GEOM test suite runs on riscv. MFC after: 1 month		2023-11-02 14:35:37 -04:00

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
