I was running v2.6.33-rc2-187-g08d869a and everything was ok. Today I
decided to update the kernel (to v2.6.33-rc4) and a minute or two after
logging into the gnome desktop this kernel bug appeared in dmesg. I then
went back to the old kernel but the bug didn't disappear, not even after
running btrfsck on the filesystem.
Ok will you please run with this patch? It shouldn't panic your box, since it
seems ret is -EEXIST. Just watch your logs for
OH NO, ORPHAN ENTRY ALREADY EXISTS FOR<number>
and then look up and find all occurances of
Btrfs: orphan add<number>
with the stack trace and send it back to me so I can verify that nothing heinous
is happening. I assume we're just racing with unlink/rename so all that needs
to be done is to take that BUG_ON out, but it would be nice to know for sure.
