spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-07-25T15:13:49+00:00

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

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

2017-11-27T15:15:37+00:00

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.

Introduce the "ruleset=number" option for devfs(5) mounts.

2012-02-09T10:09:12+00:00

Add support for updating the devfs mount (currently only changing the
ruleset number is supported).
Check mnt_optnew with vfs_filteropt(9).

This new option sets the specified ruleset number as the active ruleset
of the new devfs mount and applies all its rules at mount time. If the
specified ruleset doesn't exist, a new empty ruleset is created.

Add reference counting for devfs paths containing user created symbolic

links. The reference counting is needed to be able to determine if a
specific devfs path exists. For true device file paths we can traverse
the cdevp_list but a separate directory list is needed for user created
symbolic links.

Add a new directory entry flag DE_USER to mark entries which should
unreference their parent directory on deletion.

A new function to traverse cdevp_list and the directory list will be
introduced in a separate commit.

Modify devfs_fqpn() for future use in devfs path reference counting

2010-09-21T16:49:02+00:00

code:

- Accept devfs_mount and devfs_dirent as the arguments instead of a
  vnode. This generalizes the function so that it can be used from
  contexts where vnode references are not available.
- Accept NULL cnp argument. No '/' will be appended, if a NULL cnp is
  provided.
- Make the function global and add its prototype to devfs.h.
