- add many missing shared-library dependencies
- remove many unnecessary shared-library dependencies
- add many missing files to the Mesa source list
- fix the ordering of the SUBDIR list in the top level
to match the actual inter-library dependencies
Since the status is now used by ucom(4) driver for Carrier Detect,
and the CLOCAL flag has been required.
By this change, we assume DCD is always on. The CLOCAL flag is not
required now.
so that user can fix the ucom unit number by config file.
ex. ucom0 at ukyopon? portno 1 # modem port
ucom1 at ukyopon? portno 2 # data transfer port
The description of the locator was added to the manual page by someone,
but it has been useless until now. :)
is the first step to make PCIC run without byteswapping - which is
necessary for X server support. Current macros are still just a
kludgy shim over struct syntax, but accesses to PCIC in the .c files
are now marked up properly.
implementation of getpages and putpages and the use of UBC in the read and
write operations), the worst problem has gone away which was a panic when
a file's contents were modified in the original file system and then read
through the NFS mount point.
Also remove the entry about optimization. While tmpfs still has room for
improvement, it has become a lot better lately, thanks to the string pools
and the changes yamt@ did in the anonymous objects handling.
tmpfs' "API" and was already rotting.
Instead, merge all the relevant comments into the code. This includes
acknowledgements to Google's Summer of Code 2005 program (they were in the
AUTHORS section of tmpfs(9) before), so all the files need to be changed
to include this sentence alongside the title. (Note that this was not a
requirement of the program.)
to modify it (I hope this is the correct way to go). Avoids triggering an
assertion in the tmpfs_dir_detach function, shown by the t_rename
regression test.
- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
file sys/nfs/nfs_export.c. The former was becoming large and its code
is always compiled, regardless of the build options. Using the latter,
the code is only compiled in when NFSSERVER is enabled. While doing this,
also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
path and a set of export entries. At the moment it can only clear the
exports list or append entries, one by one, but it is done in a way that
allows setting the whole set of entries atomically in the future (see the
comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
that it becomes file system agnostic. In fact, all this whole thing was
done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
exports initialization; done internally by the kernel when initializing
the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
subsystems can run arbitrary code upon receipt of specific VFS events.
At the moment, this only provides support for unmount and is used to
destroy NFS exports lists from the file systems being unmounted, though it
has room for extension.
Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.
