sys/dev/disk/dm: Remove read/write support for /dev/mapper/control

It's obvious that /dev/mapper/control has nothing to read/write.
Running below results in kernel panic as the code requires properly
initialized a per-table lock while this chrdev has no tables mapped.
(control chrdev and dm blkdevs use the same dm device structures)

3 weeks agosys/vfs/hammer: Ask before reblocking on volume-del

sys/vfs/hammer: Ask before reblocking on volume-del

hammer volume-del finishes instantly if the volume doesn't need
reblocking, but it could take long depending on how much of the
big-blocks within the volume is used.

This commit makes hammer volume-del ask y/n whether to start
reblocking or not if the volume wasn't empty. Using force option
(-F) makes it reblock without asking.

Also note that reblocking doesn't guarantee anything on removing
a volume from filesystem. It just tries to move data to other
volume(s) so the volume may become empty. Thus users should have
choice.

sbin/hammer: Make hammer commands print root volume path

Base on the change made by the previous commit, this commit adds
the root volume path information (not root volume#) to hammer info
and hammer volume-list commands. hammer volume-list shows the path
only on -v. This enables users to explicitly know the root volume.

4 weeks agosys/vfs/hammer: Add vol_no field to struct hammer_ioc_volume

sys/vfs/hammer: Add vol_no field to struct hammer_ioc_volume

The problem with interface/commands HAMMER provides is that there
is no way to know what the volume# is for each block device once
newfs_hammer is done, while error messages and manpages, etc talk
about the root volume without explaining what that really is.
In order to clearly show what the root volume is, userspace hammer
commands need to be able to retrieve relation between HAMMER
volume# and block device path, and then print the block device
with volume# 0.

e914c91d which added hammer volume-list command should have added
volume# field to the ioctl structure or at least assign reserved
space for future extension. This is basically the only ioctl that
can retrieve block device paths, but all it does is get the paths
without any other related information. This commit adds volume#
field to struct hammer_ioc_volume.

This commit affects HAMMERIOC_ADD_VOLUME, HAMMERIOC_DEL_VOLUME,
and HAMMERIOC_LIST_VOLUMES ioctls. These are only used by hammer
volume-add, volume-del, volume-list and volume-blkdevs commands.
This commit requires both /sbin/hammer and kernel rebuild.
