890e036b3c Implement d_discard for dk. This closes PR 47940. 2014-07-25 08:23:56 +00:00

f9228f4225 Add d_discard to all struct cdevsw instances I could find. 
All have been set to "nodiscard"; some should get a real implementation.

8c70ef39af Add d_discard to all struct bdevsw instances I could find. 
I've set them all to nodiscard. Some of them (wd, dk, vnd, ld,
raidframe, maybe cgd) should be implemented for real.

a68f9396b6 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.

device names. Fall back to classic device names when the label has an
empty name or the default name 'fictitious'.

d4145bf15d minor mostly cosmetical fixes: use designated type for device major 
numbers, typo in comment, misuse of minor()
(the latter one is not cosmetical, but would only affect systems
with more than 256 disk wedges)

e225b7bd09 Welcome to 5.99.53! Merge rmind-uvmplock branch: 
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

f5a8179a2f Make sure to release sc_parent->dk_rawlock before calling 
vn_close(sc->sc_parent->dk_rawvp). Avoids a lockdebug panic:
error: mutex_destroy: assertion failed: !MUTEX_OWNED(mtx->mtx_owner) && !MUTEX_HAS_WAITERS(mtx)
when the parent is a raidframe device.

3446f432fa dkwedge_list() is currently called only from ioctl routines where 
l == curlwp.  Since there is no perceived case where we'd ever want
to copy the list to non-curlwp, simplify the code a bit.
(the struct lwp * argument could probably be dropped too, but
that's another commit)

5a4d67314b Extract a lot of code from dkwedge_del(), and move it to dkwedge_detach() 
to create a comprehensive detachment hook.  Let that hook run at
shutdown.  Now, 'drvctl -d dk0' actually deletes a wedge if it is
not in-use (otherwise fails w/ EBUSY), and wedges are gracefully
detached from their "parent" at shutdown.

f6a70673ba Mark a buffer busy in getnewbuf() when it came from the pool_cache since 
its not on a free list.

Also change buf_init() to not automatically mark buffers `busy' since this
only makes sense for bufcache buffers.

Mark all buf_init'd buffers 'busy' on the places where they ought to be
flagged as such to not confuse the buffer cache.

Fixes PR 38923.

5e306eb1c9 Split device_t/softc. Well, there's not much to split there, as the 
device_t didn't contain the softc anyway.

This driver should be re-structured so it doesn't have to manage its own
set of softcs.
