Staging: comedi: addi-data: fix brace-related coding style issues in hwdrv_apci035.c

This patch for hwdrv_apci035 removes some unneeded braces, and moves some
improperly placed braces to the correct position, as found by checkpatch.
It also removes a commented out if-statement that I found whilst cleaning
braces that is identical to another un-commented if-statement directly
above it, so it is just added clutter and so we can delete it to clean up
further.

staging: ion: Add private buffer flag to skip page pooling on free

Currently, when we free a buffer it might actually just go back into a
heap-specific page pool rather than going back to the system. This poses
a problem because sometimes (like when we're running a shrinker in low
memory conditions) we need to force the memory associated with the
buffer to truly be relinquished to the system rather than just going
back into a page pool.

There isn't a use case for this flag by Ion clients, so make it a
private flag. The main use case right now is to provide a mechanism for
the deferred free code to force stale buffers to bypass page pooling.

staging: ion: Move shrinker out of heaps

Every heap that uses deferred frees is going to need a shrinker
to shrink the freelist under memory pressure.  Rather than
requiring each heap to implement a shrinker, automatically
register a shrinker if the deferred free flag is set.
The system heap also needs to shrink its page pools, so add
a shrink function to the heap ops that will be called after
shrinking the freelists.

Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.

Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

 "Two urgent fixes in the tracing utility.

  The first is a fix for the way the ring buffer stores timestamps.
  After a restructure of the code was done, the ring buffer timestamp
  logic missed the fact that the first event on a sub buffer is to have
  a zero delta, as the full timestamp is stored on the sub buffer
  itself.  But because the delta was not cleared to zero, the timestamp
  for that event will be calculated as the real timestamp + the delta
  from the last timestamp.  This can skew the timestamps of the events
  and have them say they happened when they didn't really happen.
  That's bad.

  The second fix is for modifying the function graph caller site.  When
  the stop machine was removed from updating the function tracing code,
  it missed updating the function graph call site location.  It is still
  modified as if it is being done via stop machine.  But it's not.  This
  can lead to a GPF and kernel crash if the function graph call site
  happens to lie between cache lines and one CPU is executing it while
  another CPU is doing the update.  It would be a very hard condition to

Btrfs: unset DCACHE_DISCONNECTED when mounting default subvol

A user was running into errors from an NFS export of a subvolume that had a
default subvol set.  When we mount a default subvol we will use d_obtain_alias()
to find an existing dentry for the subvolume in the case that the root subvol
has already been mounted, or a dummy one is allocated in the case that the root
subvol has not already been mounted.  This allows us to connect the dentry later
on if we wander into the path.  However if we don't ever wander into the path we
will keep DCACHE_DISCONNECTED set for a long time, which angers NFS.  It doesn't
appear to cause any problems but it is annoying nonetheless, so simply unset
DCACHE_DISCONNECTED in the get_default_root case and switch btrfs_lookup() to
use d_materialise_unique() instead which will make everything play nicely
together and reconnect stuff if we wander into the defaul subvol path from a
different way.  With this patch I'm no longer getting the NFS errors when
exporting a volume that has been mounted with a default subvol set.  Thanks,

Btrfs: fix max_inline mount option

max_inline=0.  Any other value that is supplied to max_inline will be
adjusted to a minimum of 4k.  Since max_inline has an effective maximum

The reason is that we get to call cond_resched_lock(&head_ref->lock) while
still holding @delayed_refs->lock.

So it's different with __btrfs_run_delayed_refs(), where we do drop-acquire
dance before and after actually processing delayed refs.

Here we don't drop the lock, others are not able to add new delayed refs to
head_ref, so cond_resched_lock(&head_ref->lock) is not necessary here.

  during the 3.12 cycle, fixes for two bugs in the ACPI core introduced
  recently and a MAINTAINERS update related to cpufreq.

  Specifics:

   - Fix for a recent regression in the intel_pstate driver that
     introduced a race condition causing systems to crash during
     initialization in some situations.  This removes the affected code

     causing devices to be dropped as a result of bus check
     notifications after system resume on some systems due to the way
     ACPIPHP interprets _STA return values (arguably incorrectly).  From
     Mika Westerberg.

   - ACPI dock driver fix for a problem causing docking to fail due to a
     check that always fails after recent ACPI core changes (found by
     code inspection).

   - ACPI container driver fix to prevent memory from being leaked in an

Remove the unnecessary check of 'cmd->chanlist_len > 0'. The (*do_cmdtest) already
validated this before the (*do_cmd) was called.

10 years agostaging: comedi: don't clear 'data' on (*insn_read) timeout

staging: comedi: don't clear 'data' on (*insn_read) timeout

It's not necessary to clear the returned data pointer when an (*insn_read)
times out. For aesthetics, remove all of these in the drivers.

Have the comedi core display a standard dev_dbg() message when a timeout
occurs and remove all the driver specific messages.

10 years agostaging: comedi: dmm32at: use comedi_timeout()

staging: comedi: dmm32at: use comedi_timeout()

Use comedi_timeout() to wait for the analog input settle and end-of-
conversion. These tests use different registers but the same bit so
the register is passed as the 'context'. The same test is used in
dmm32at_ai_cmd() but the 'insn' is not available. This is ok since
the test function, and comedi_timeout() don't use it.

Use comedi_timout() to wait for the analog output end-of-conversion.
