-		ftrace - Function Tracer
-		========================
-
-Copyright 2008 Red Hat Inc.
-Author: Steven Rostedt <srostedt@redhat.com>
-
-
-Introduction
-------------
-
-Ftrace is an internal tracer designed to help out developers and
-designers of systems to find what is going on inside the kernel.
-It can be used for debugging or analyzing latencies and performance
-issues that take place outside of user-space.
-
-Although ftrace is the function tracer, it also includes an
-infrastructure that allows for other types of tracing. Some of the
-tracers that are currently in ftrace is a tracer to trace
-context switches, the time it takes for a high priority task to
-run after it was woken up, the time interrupts are disabled, and
-more.
-
-
-The File System
----------------
-
-Ftrace uses the debugfs file system to hold the control files as well
-as the files to display output.
-
-To mount the debugfs system:
-
-  # mkdir /debug
-  # mount -t debugfs nodev /debug
-
-
-That's it! (assuming that you have ftrace configured into your kernel)
-
-After mounting the debugfs, you can see a directory called
-"tracing".  This directory contains the control and output files
-of ftrace. Here is a list of some of the key files:
-
-
- Note: all time values are in microseconds.
-
-  current_tracer : This is used to set or display the current tracer
-		that is configured.
-
-  available_tracers : This holds the different types of tracers that
-		has been compiled into the kernel. The ...

Why?  There is no ftrace code in the 2.6.26 kernel, so why would we
worry about keeping such documentation up to date, let alone even
present at all?

Why should this matter?

Greg,

Don't get me wrong. I agree with the reason to pull it. It is the right 
thing to do. But still, I don't like it, not because I disagree with it, 
but simply, I liked the fact that the document made it in before the code.

I just sold my 1994 Nissan Sentra because I seldom drove it. It was the 
right thing to do. But I still don't like the fact that I don't have it 
anymore.

I don't like it. This is a feeling. Nothing to do with being technical. 
Hence, I will not argue it.  I just want it on record that I do not 
_like_ it. ;-)

My objection was only symbolic.

2.6.26-stable review patch.  If anyone has any objections, please let us

------------------

From: Linus Torvalds <torvalds@linux-foundation.org>

commit 0056e65f9e28d83ee1a3fb4f7d0041e838f03c34 upstream

We zero-fill them like we are supposed to, and that's all fine.  It's
only an error if the 'romfs_copyfrom()' routine isn't able to fill the
data that is supposed to be there.

Most of the patch is really just re-organizing the code a bit, and using
separate variables for the error value and for how much of the page we
actually filled from the filesystem.

netfilter: nf_nat_sip: c= is optional for session

Upstream commit c71529e4:

According to RFC2327, the connection information is optional
in the session description since it can be specified in the
media description instead.

My provider does exactly that and does not provide any connection
information in the session description.  As a result the new
kernel drops all invite responses.

This patch makes it optional as documented.

[SCSI] bsg: fix bsg_mutex hang with device removal

We don't need to hold bsg_mutex during bsg_complete_all_commands(). It
leads to a problem that we block bsg_unregister_queue during
bsg_complete_all_commands (untill all the outstanding commands
complete).

Thanks to Pete Wyckoff for finding the bug and testing the patch.

[ Upstream commit f48ed538386cb41559282d989354e8f5d442d71c ]

There is a possible race in md_probe.  If two threads call md_probe
for the same device, then one could exit (having checked that
->gendisk exists) before the other has called kobject_init_and_add,
thus returning an incomplete kobj which will cause problems when
we try to add children to it.

So extend the range of protection of disks_mutex slightly to
avoid this possibility.

how I love this stuff...

Ok, do_debug() is a trap, this can happen at any time regardless of the
machine's IRQ state. So the first thing we do is fix up the IRQ state.
Then we call this die notifier stuff; and return with messed up IRQ
state... YAY.

So, kprobes fudges it..

  notify_die(DIE_DEBUG)
    kprobe_exceptions_notify()
      post_kprobe_handler()
        modify regs->flags
        trace_hardirqs_fixup_flags(regs->flags);  <--- must be it

So what's the use of modifying flags if they're not meant to take effect
at some point.

/me tries to reproduce issue; enable kprobes test thingy && boot

OK, that reproduces..

So the below makes it work - but I'm not getting this code; at the time
I wrote that stuff I CC'ed each and every kprobe maintainer listed in
the usual places but got no reposonse - can some please explain this
stuff to me?

Are the saved flags only for the TF bit or are they made in full effect
later (and if so, where) ?

    sorts of bad things to happen.

    This patch fixes the problem by using the new function,
    device_create_drvdata().  It fixes the problem in all of the scsi
    drivers that need it.

The problem is ch_probe stores ch's private data at a wrong place.

We need to store it at scsi_device->sdev_gendev but the above patch
stores it at device struct that device_create_drvdata returns. So we
hit an oops when ch_remove accesses
scsi_device->sdev_gendev->driver_data, which is NULL.

Actually, there wasn't a race because ch doesn't create sysfs files
with device struct that device_create returns. This patch puts back
dev_set_drvdata() to set ch's private data properly.

commit 9ad593f6d326e7a4664e3856520f6c042f82a37f upstream

Many HD-audio controllers seem inaccurate about the IRQ timing of
PCM period updates.  This has caused problems on audio quality; e.g.
JACK doesn't work with two periods.

This patch fixes the problem by checking the current DMA position
at IRQ handler and delays the period-update via a workq if it's
inaccurate.

There might be another device requiring a similar fix, too (or fix for

commit d70b67c8bc72ee23b55381bd6a884f4796692f77 upstream

Lookup can install a child dentry for a deleted directory.  This keeps
the directory dentry alive, and the inode pinned in the cache and on
disk, even after all external references have gone away.

This isn't a big problem normally, since memory pressure or umount
will clear out the directory dentry and its children, releasing the
inode.  But for UBIFS this causes problems because its orphan area can
overflow.

Fix this by returning ENOENT for all lookups on a S_DEAD directory
before creating a child dentry.

Thanks to Zoltan Sogor for noticing this while testing UBIFS, and
Artem for the excellent analysis of the problem and testing.

commit 3a0f2c871849f23c1070965bf94dec3f9c0b479d upstream

When signal is noisy, hardware can use all RX buffers and since the last
entry in the list is self-linked, it overwrites the entry until we link
new buffers.

Ensure that we don't free this last one until we are 100% sure that it
is not used by the hardware anymore to not cause memory curruption as
can be seen below.

This is done by checking next buffer in the list. Even after that we
know that the hardware refetched the new link and proceeded further
(the next buffer is ready) we can finally free the overwritten buffer.

We discard it since the status in its descriptor is overwritten (OR-ed
by new status) too.

commit 3f31fddfa26b7594b44ff2b34f9a04ba409e0f91 upstream

journal_try_to_free_buffers() could race with jbd commit transaction when
the later is holding the buffer reference while waiting for the data
buffer to flush to disk.  If the caller of journal_try_to_free_buffers()
request tries hard to release the buffers, it will treat the failure as
error and return back to the caller.  We have seen the directo IO failed
due to this race.  Some of the caller of releasepage() also expecting the
buffer to be dropped when passed with GFP_KERNEL mask to the
releasepage()->journal_try_to_free_buffers().

With this patch, if the caller is passing the __GFP_WAIT and __GFP_FS to
indicating this call could wait, in case of try_to_free_buffers() failed,
let's waiting for journal_commit_transaction() to finish commit the
current committing transaction, then try to free those buffers again.

From: Marcel Holtmann <marcel@holtmann.org>

commit ec8dab36e0738d3059980d144e34f16a26bbda7d upstream

When using the HIDP or BNEP kernel support, the user-space needs to
know if the connection has been terminated for some reasons. Wake up
the application if that happens. Otherwise kernel and user-space are
no longer on the same page and weird behaviors can happen.

From: Andreas Schwab <schwab@suse.de>

commit e4cc58944c1e2ce41e3079d4eb60c95e7ce04b2b upstream

Current versions of gdb require a working implementation of
PTRACE_GETSIGINFO for proper watchpoint support.  Since struct siginfo
contains pointers it must be converted when passed to a 32-bit debugger.
