Hi,
I'm reading the mkfs code, and confused by its -A option.

the start of the filesystem. But mkfs will always zero some area
at the beginning of the first dev, regardless -r specified or not.
My question is:
Why mkfs zeros the

The receive code was not distinguishing properly between the mount root
and the directory to create the received subvolume in.
Also make sure the find_mount_root reports an error if it cannot find
a match at all.

I recently got some checksum errors on my btrfs filesystem that seem
"interesting". This is on a F18 kernel (3.6.0-3.fc18.x86_64) with the
filesystem on a single INTEL SSDSA2CW16 disk (ssd). Its my workstation,
so i do normal development on it, i.e. its not a server. Recently I have
been doing some
This patch also requires a change in the user-space part of "receive".
We need to use "lchown" instead of "chown". We will do this in the
following patch.

If a subvolume is deleted between __list_subvol_search() and
__list_subvol_fill_paths(),
the tool would have stopped with an error. So drop those subvolumes
that did not have ROOT_BACKREF, and those
for whom a path component to the parent root was missing.
