Subject: vfs: leverage bd_super in get_active_super
Using get_active_super will not work properly if the fs (like btrfs) does not
save its s_bdev with the device it is on. Also it does not provide the entire
picture, since an filesystem can be contained on multiple disks (again like
btrfs).
Subject: btrfs: store pointer to superblock in bd_super
This is needed to get get_active_super and, by extension, thaw_bdev initiated
freezes working.
Thanks go to Josef Bacik and Christoph Hellwig for initiating this effort
to fix btrfs and for suggesting the solution implemented here,

Hi Mitch,
for issue (1) I proposed a small patch here:
http://www.spinics.net/lists/linux-btrfs/msg19574.html
which resolves it for me. The problem is that there are subvolumes
that still exist in the root tree, but don't have their ROOT_BACKREF
entry anymore.
However, Miao's rework of the

The idea of the btrfs send stream format was to generate it in a way that
it is easy to receive on different platforms. Thus the proposed name FITS, for

If the path to a given loopback file is longer than 64 characters, none of the
Btrfs-progs tools can use it. This is because the size of loopinfo.lo_name

The attached patch fixes this by fetching

The LOOP_GET_STATUS ioctl truncates filenames to 64 characters. We should get

For kicks, I started doing a btrfs balance on filesystem A
yesterday. At some point, a process (a backup script which uses
rsync) ran which did a lot of I/O on A and then proceeded to a lot of
I/O on filesystem B (also btrfs) as well. At some point, I got a BUG
