Date: Tue, 26 Jul 2011 10:51:24 +0300	[thread overview]
Message-ID: <CAA_Wi2K7w9mwGS3LO-eEydZ3R6fSeQWOSoNz6dNMkO4w8DohsQ@mail.gmail.com> (raw)

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....
