I found another bug. There are codes (btrfs_save_ino_cache) that
modify fs trees after
create_pending_snapshots is called. This can corrupt your fs.

I encountered following panic using 'btrfs-unstable + for-linus'
kernel.
I ran btrfs fi bal /test5 command, and mount option of /test5
is as follows:
/dev/sdc3 on /test5 type btrfs
(rw,space_cache,compress=lzo,inode_cache)
So, just a btrfs fi bal would lead to the bug?
I
Add a mutex to btrfs_init_reloc_root() to prevent the reloc tree
creation from concurrent execution.

Thanks!
Unfortunately I can still encounter BUG() in difference places in
each run:
kernel BUG at fs/btrfs/extent-tree.c:6173!
kernel BUG at fs/btrfs/volumes.c:2567!

The usage of trans_mutex in relocation code is subtle. It controls
interaction of relocation
with transaction start, transaction commit and snapshot creation.
Simple replacing
trans_mutex with trans_lock is wrong.
