Hi! Mounting a Btrfs seed filesystem (read-only, with no writable devices
added to it) and then running df results in a kernel "invalid opcode" dump and
the filesystem being unmountable (although it can still be used as a base for
other filesystems). An easy way to trigger the error is shown below (using a
loop device, though the error also happens with "real" block devices)::
## create filesystem image ##
root@sid386:/tmp# dd if=/dev/zero of=myfs-ro.btr bs=1M seek=2048 count=0
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00041391 s, 0.0 kB/s
## create filesystem on image ##
root@sid386:/tmp# mkfs.btrfs myfs-ro.btr
WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL
WARNING! - see http://btrfs.wiki.kernel.org before using
fs created label (null) on myfs-ro.btr
nodesize 4096 leafsize 4096 sectorsize 4096 size 2.00GB
Btrfs Btrfs v0.19
## enable seeding on the filesystem ##
root@sid386:/tmp# btrfstune -S 1 myfs-ro.btr
## mounting with "-o ro" gives the same result ##
root@sid386:/tmp# mount -o loop myfs-ro.btr /mnt
mount: block device /tmp/myfs-ro.btr is write-protected, mounting read-only
root@sid386:/tmp# df
## the error shows up at this point, see kernel log ##
root@sid386:/tmp# umount /mnt
umount: /mnt: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
Thanks!

It'd be great if you could help the patch make its way to upstream. Thanks! -- Ivan Vilata i Balaguer -- https://elvil.net/
