I just sent out a patch to fix it, see:

[PATCH] Btrfs: reverse enough space for file clone

Re: kernel BUG at fs/btrfs/delayed-inode.c:1693!

[Markus Suvanto]

=46ilesystem is almost empty:
/dev/mapper/vg_md1-btrfs
                      155G  2,1G  152G   2% /mnt/btrfs

=46ile system is made using command
mkfs.btrfs /dev/mapper/vg_md1-btrfs

If you can't reproduce this I can try to compile kernel
using debug stuff....

Appears to be an unhandled ENOSPC error; hard to tell much else
without the debug info and the details on the volume (size, mkfs args,
etc).

kernel BUG at fs/btrfs/delayed-inode.c:1693!

[Markus Suvanto]

This is what I get  if I use command:
bcp file file_copy
I can reproduce this every time when using bcp command.

Filesystem is under lvm:
/dev/mapper/vg_md1-btrfs on /mnt/btrfs type btrfs (rw,noatime,subvol=.)

This filesystem is created using linux-3.0 and
mkfs.btrfs, part of Btrfs v0.19-1-g4f89b6e-dirty

Ok, I don't have any kernel debug stuff there but maybe you can
reproduce this....
