Subject: btrfs: store pointer to superblock in bd_super

to fix btrfs and for suggesting the solution implemented here, respectiv
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).

This will add a sub command to show information about a subvol.
eg:

This set of patch will add show sub-command to
btrfs subvolume, which is to show more information
about a given subvol or snapshot. At present it shows
3 info, I hope this will be further useful if enhanced
as needed.
eg:
# btrfs su show /btrfs/sssv3
/btrfs/sssv3

Hi Rory,
my kernel is slightly different, but the send-receive kernel code that
I use is on the same commit. However, the issue you are hitting is
most probably not a kernel issue. The receive part works totally in
user-space. To confirm that, maybe you can post somewhere the full-

Hi Rory,
all your tests work perfectly for me (really, I swear:)), with exact
same mount points and subvol/snap/dir names.
Just to make that the patch some how did not get messed up in the
