When editing cmds-filesystem.c, I found cmd_filesystem_df() uses 7

quite embarrassing.
Such problem is especillay hard to detect when reviewing patches,

When calling find_mount_root(), caller in fact wants to find the mount

So also check ent-fstype in find_mount_root() and output proper error

What do you mean by that?

I want to increase the size of the vdev, not just the zpool. I want to
make a 3-drive array into a 4-drive array by adding a single drive

When a btrfs has multiple devices (e.g. /dev/sdb, /dev/sdc), how
should I interpret disk_bytenr in btrfs_file_extent_item?
Does it depend on the striping config? Say I used raid0, then
disk_bytenr 0~64K will be on /dev/sdb, and 64K~128K on /dev/sdc?
Thanks,

Given something like that, you'd just replace the calls to sleep with
'btrfs fi synctheworldandwait' and know that on return, the actions you
just queued up completed.
I'll admit to not really knowing what I'm talking about
I'm trying to use serialized BTRFS snapshots as a backup system. The problem is
that I don't know how to avoid sending duplicate data and also have the ability
to prune old backups.
Specifically I've considered the following:

btrfs subvolume snapshot -r live-volume volume-date
