Package: btrfs-tools
Version: 0.19+20111105-2
Severity: normal
File: /sbin/btrfs

Dear Maintainer,
I found a behavior which looks like a bug.
Namely, being inside a snapshot directory, I can't create a file/directory
with the name of the snapshot directory.

For example, inside /mnt/aSnap, I can't create a file named 'aSnap', so I'm
filling this bug report.

Below follows full reproduction of this behavior:

aris tmp # dd if=/dev/zero of=FILE bs=4k seek=`echo 5*1024*1024 | bc` count=1

aris tmp # mkfs.btrfs -Ltest /dev/loop0
