Bug#948782: linux: Request for CONFIG_DM_CLONE=m on 5.4+

[Nikos Tsironis <ntsironis@arrikto.com>]

Source: linux
Version: 5.4.8-1
Severity: normal

Dear Debian kernel maintainers,

Could you consider enabling the dm-clone device mapper target as a
module from the 5.4 kernel and onwards?

dm-clone produces a one-to-one copy of an existing, read-only source
device into a writable destination device. The cloned device is
visible/mountable immediately and the copy of the source device to the
destination device happens in the background, in parallel with user I/O.

Thanks,
Nikos Tsironis
