Hello,
I was running "btrfs fi balance start -dusage=5 -musage=5 -v /" on 3.5.0, and
soon these BUG happened. Then some fs syscalls started to block (in mutt, find,
...), and after a while the computer (remote) stopped responding by ssh. After
rebooting, the balance continued fine.
I attach dmesg.txt, and the disasm of insert_inline_extent_backref. That disasm
was a bit tricky; my objdump does not seem to understand the btrfs.ko.
binutils 2.21.1a objdump fails: file format not known
binutils 2.22 objdump fails: bad value
elfutils objdump works, but does not understand symbols. Full text disasm.
binutils readelf works.
I took the address reported by binutils readelf, and seeked using the elfutils
objdump.
If anyone wants to test, here is the module: http://viric.name/tmp/btrfs.ko.bz2
The module is built with "-gdwarf-4". Maybe that breaks objdump.
(I'm not subscribed, please keep me in Cc)
Regards,
Lluís.

Am I right that it is not in 3.5.1?

I don't believe fixes can be considered for stable releases until
they're in the mainline, so until Linus processes that last merge
request from Chris it can't happen (and he's not done so yet).
That said, there was one btrfs fix merged into 3.5.1:
Chris Mason (1):
Btrfs: call the ordered free operation without any locks held
But I suspect that is not the fix you are looking for..
cheers,
Chris

Right, this fix was bigger than we could send to stable yet. For now
you need to run my for-linus tree against 3.5 (or 3.5.1) for the fixes.
