Hello Tomasz,
Chris recently sent a patch that addressed a race condition with

I could still see the bug (below) with 3.13 and tried to apply the patch.
It did apply:
patching file fs/btrfs/ctree.c
Hunk #1 succeeded at 39 with fuzz 2.
Hunk #2 succeeded at 475 (offset 1 line).
Hunk #3 succeeded at 485 (offset 1 line).
Hunk #4 succeeded at 505 (offset 1 line).
Hunk #5 succeeded at 527 (offset 1 line).
Hunk #6 succeeded at 568 (offset 1 line).
Hunk #7 succeeded at 578 (offset 1 line).
Hunk #8 succeeded at 606 (offset 1 line).
Hunk #9 succeeded at 703 (offset 1 line).
Hunk #10 succeeded at 742 (offset 1 line).
Hunk #11 succeeded at 834 (offset 1 line).
Hunk #12 succeeded at 927 (offset 1 line).
Hunk #13 succeeded at 1230 (offset 1 line).
Hunk #14 succeeded at 3216 (offset -42 lines).
Hunk #15 succeeded at 3291 (offset -42 lines).
Hunk #16 succeeded at 3497 (offset -42 lines).
however, the kernel fails to compile:
LD fs/btrfs/built-in.o
CC [M] fs/btrfs/super.o
CC [M] fs/btrfs/ctree.o
fs/btrfs/ctree.c: In function ‘tree_mod_log_set_node_key’:
fs/btrfs/ctree.c:924:2: error: implicit declaration of function ‘__tree_mod_log_insert_key’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[4]: *** [fs/btrfs/ctree.o] Error 1
Is there a patch which works with 3.13?
