Greetings,
We hit the below bug when doing write tests to btrfs.
Other filesystems (ext4, xfs) works fine. 2 full dmesgs are attached.
196d38bccfcfa32faed8c561868336fdfa0fe8e4 is the first bad commit

block: Generic bio chaining
This adds a generic mechanism for chaining bio completions. This is
going to be used for a bio_split() replacement, and it turns out to be
very useful in a fair amount of driver code - a fair number of drivers
were implementing this in their own roundabout ways, often painfully.
Note that this means it's no longer to call bio_endio() more than once
on the same bio! This can cause problems for drivers that save/restore
bi_end_io. Arguably they shouldn't be saving/restoring bi_end_io at all
- in all but the simplest cases they'd be better off just cloning the
bio, and immutable biovecs is making bio cloning cheaper. But for now,
we add a bio_endio_nodec() for these cases.

Looks like Kent missed the btrfs endio in the original commit. How
about this patch:
---------
In btrfs_end_bio, call bio_endio_nodec on the restored bio so the
bi_remaining is accounted for correctly.

Interestingly, the BUG message disappeared but it blocks the test run.
In the end, the test watchdog reboots the machine with SysRq:
2014-01-04 23:13:02 mount -t btrfs /dev/vda /fs/vda
[ 20.184264] btrfs: device fsid f0e06999-0518-47e0-a622-21b8749438be devid 1 transid 4 /dev/vda

Attached is the full dmesg for a good run (v3.13-rc7) and a bad run
(this patch).
Thanks,

Chris, the patch below seems to be incorrect - with it we get hangs, so
bi_remaining (probably) isn't getting decremented when it should be. You sent
Jens fixes for btrfs which I somehow lost when I rebased, do you remember how
this is supposed to work? Looking at the code I'm not quite sure what's going on
here.

OK, after a bit more staring I believe the correct fix is the following.
Fengguang, Please try this one?
Regards,
Muthu
------------
In btrfs_end_bio(), we increment bi_remaining if is_orig_bio. If not,
we restore the orig_bio but failed to increment bi_remaining for
orig_bio, which triggers a BUG_ON later when bio_endio is called. Fix
is to increment bi_remaining when we restore the orig bio as well.

This code still confuses me but I think you're correct, the fix certainly
matches the evidence we have.

Thanks Fengguang. Final patch with added comment. BTW, fengguang
mentioned that git-am has trouble with the inline patch and "quilt
import" worked fine for him...
------------
In btrfs_end_bio(), we increment bi_remaining if is_orig_bio. If not,
we restore the orig_bio but failed to increment bi_remaining for
orig_bio, which triggers a BUG_ON later when bio_endio is called. Fix
is to increment bi_remaining when we restore the orig bio as well.

Hi everyone,
Which git tree is this against? Just Jens or some extra code too?
I'll run some tests here. My original patch is below (it's slightly
different from Muthu's).
Btrfs is sometimes calling bio_endio twice on the same bio while
we chain things. This makes sure we don't trip over new assertions in
fs/bio.c

Chris,
This is based off of Jens block tree, for-3.14/core branch...

Ok, Kent did pull in one of my hunks, one was a comment and the third
was effectively the same as your patch. I tried to test the end result
today, but get these on boot with ext4:

Chris,

[ 8.336062] bio_endio: bio for (unknown) without endio
This is my recent change to avoid memory leak in bio_endio. But I
think the problem is higher up, most likely bio_endio is called twice
on the same bio (which was freed before).
Are you running the unmodified for-3.14/core or do you have local patches?
Regards,
Muthu

It's for-3.14/core with my btrfs branch. Basically rc7 instead of rc6
but no changes to the block layer. I hadn't mounted btrfs yet.

Not really... the BUG that is triggered:
kernel BUG at fs/bio.c:523!
It is in bio_put() (added to bio_endio() as part of recent change)
which gets an already freed bio.

But, like I said, problem is in different place. I am running a "dd"
on ext4 fs for a while now, but didn't hit the problem. Any idea to
repro locally? I would also suggest running just the for-3.1/core to
isolate the issue.

Just reverting that change fixes it for me. Jens mentioned it was
broken for on-stack bios.

On-stack bios? I don't recall ever coming across such a thing, who what
where why?
i would expect on stack bios to work though, i'm really curious how it
was broken

New change added a bio_put() which might not work if the bio is on stack.
I don't remember seeing a on-stack-bio either, any help to jog my memory?

That's code that logically belongs in bio_chain_endio(), it's just a
hack to avoid blowing the stack since the kernel is compiled with
-fno-sibling-call-optimization when you enable frame pointers (otherwise
would optimize those tail calls to jumps and we'd have no stack blowing
issues).
