ad | Move proc_lock into the data segment. It was dynamically allocated because
at the time we had mutex_obj_alloc() but not __cacheline_aligned.

dholland | branches: 1.40.8; 1.40.18;
Add d_discard to all struct cdevsw instances I could find.
All have been set to "nodiscard"; some should get a real implementation.
|

| 16-Mar-2014 |
dholland | branches: 1.39.2;
Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Clean up vnode lock operations pass 2:
VOP_UNLOCK(vp, flags) -> VOP_UNLOCK(vp): Remove the unneeded flags argument.
Welcome to 5.99.32.
Discussed on tech-kern.

ad | branches: 1.37.2; 1.37.22; 1.37.24;
Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:
- Inspecting process state requires thread context, so signals can no longer
be sent from a hardware interrupt handler. Signal activity must be
deferred to a soft interrupt or kthread.
- As the proc state locking is simplified, it's now safe to take exit()
and wait() out from under kernel_lock.
- The system spends less time at IPL_SCHED, and there is less lock activity.

pooka | branches: 1.36.14; 1.36.16;
Remove the "struct lwp *" argument from all VFS and VOP interfaces.
The general trend is to remove it from all kernel interfaces and
this is a start. In case the calling lwp is desired, curlwp should
be used.
quick consensus on tech-kern

| 1.35 |
| 03-Apr-2007 |
hannken | branches: 1.35.8; 1.35.10; 1.35.16;
Remove calls to now obsolete vn_start_write() and vn_finished_write().
|
| 1.34 |
| 09-Mar-2007 |
ad | branches: 1.34.2; 1.34.4;
- Make the proclist_lock a mutex. The write:read ratio is unfavourable,
and mutexes are cheaper use than RW locks.
- LOCK_ASSERT -> KASSERT in some places.
- Hold proclist_lock/kernel_lock longer in a couple of places.

|
| 1.30 |
| 12-Oct-2006 |

- no more -Wno-unused for i386

| 01-Mar-2006 |
yamt | branches: 1.27.2; 1.27.4; 1.27.6;
merge yamt-uio_vmspace branch.
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
|

|

| 15-Oct-2003 |
hannken | branches: 1.23.8; 1.23.10;
Add the gating of system calls that cause modifications to the underlying
file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.
From FreeBSD with slight modifications.

fvdl | branches: 1.21.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
|
| 1.20 |
| 28-Jun-2003 |
darrenr | Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V

jdolecek | merge kqueue branch into -current
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

| 06-Sep-2002 |
gehenna | Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

fvdl | Various changes to make cloning devices possible:
* Add an extra argument (struct vnode **) to VOP_OPEN. If it is
not NULL, specfs will create a cloned (aliased) vnode during
the call, and return it there. The caller should release and
unlock the original vnode if a new vnode was returned. The
new vnode is returned locked.
* Add a flag field to the cdevsw and bdevsw structures.
DF_CLONING indicates that it wants a new vnode for each
open (XXX is there a better way? devprop?)
* If a device is cloning, always call the close entry
point for a VOP_CLOSE.
Also, rewrite cons.c to do the right thing with vnodes. Use VOPs
rather then direct device entry calls. Suggested by mycroft@
Light to moderate testing done an i386 system (arch doesn't matter
though, these are MI changes).
|
| 1.16.10.1 |
| 07-Sep-2001 |
thorpej | Commit my "devvp" changes to the thorpej-devvp branch. This
replaces the use of dev_t in most places with a struct vnode *.
This will form the basic infrastructure for real cloning device
support (besides being architecurally cleaner -- it'll be good
to get away from using numbers to represent objects).

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

device nodes for /dev/null, /dev/zero, etc.
- sys/dev: Convert rnd, wd, agp, raid, cd, sd, wsdisplay, wskbd, wsmouse,
wsmux, tty, bpf, swap to devfs New World Order.
- sys/fs/devfs: Make the visibility attribute of device nodes configurable.
Also provide a function to mount a devfs on boot.
- sys/kern: Add a new boot flag, -n. This disables devfs support. Unless
the -n flag is specified the kernel will mount a devfs file
system on boot.

| 19-Jul-2016 |
pgoyette | Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.
As suggested by riastradh@
|
| 1.40.8.1 |

pgoyette | Rump drivers are always installed via devsw_attach() so we need to
always allocate a 'struct localcount' for these drivers whenever they
are built as modules.
