Kirk McKusick c2cd605e8c Get consistent updates for UFS superblocks.
Superblocks are written by Freebsd clients using the ffs_sbput()
routine (exported from the kernel in sys/ufs/ffs/ffs_subr.c). These
clients include the kernel, some geom modules, and system utilities
using libufs. Currently backward compatible updates of UFS superblocks
are done only when the kernel writes them. These updates should be
done whenever any call to ffs_sbput() is done. This commit moves
these UFS superblock compatibility updates from the kernel-specific
superblock update to ffs_sbput() so that all clients make these
compatibility updates when they write superblocks.

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.
