An initial tidyup of the mount() syscall and VFS mount code. This code replaces the earlier work done by jlemon in an attempt to make linux_mount() work. * the guts of the mount work has been moved into vfs_mount(). * move `type', `path' and `flags' from being userland variables into being kernel variables in vfs_mount(). `data' remains a pointer into userspace. * Attempt to verify the `type' and `path' strings passed to vfs_mount() aren't too long. * rework mount() and linux_mount() to take the userland parameters (besides data, as mentioned) and pass kernel variables to vfs_mount(). (linux_mount() already did this, I've just tidied it up a little more.) * remove the copyin*() stuff for `path'. `data' still requires copyin*() since its a pointer into userland. * set `mount->mnt_statf_mntonname' in vfs_mount() rather than in each filesystem. This variable is generally initialised with `path', and each filesystem can override it if they want to. * NOTE: f_mntonname is intiailised with "/" in the case of a root mount. |

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.
