Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

This driver provides support for virtio based paravirtual device
|
|
drivers over PCI. This requires that your VMM has appropriate PCI
|
|
virtio backends. Most QEMU based VMMs should support these devices
|

(like KVM or Xen).

Virtio PCI Card 0.9.X Draft (circa 2014) and older device support.
|
|
|
|
This option enables building a transitional driver, supporting
|
|
both devices conforming to Virtio 1 specification, and legacy devices.
|
|
If disabled, you get a slightly smaller, non-transitional driver,
|
|
with no legacy compatibility.
|
|
|
|
So look out into your driveway. Do you have a flying car? If
|
|
so, you can happily disable this option and virtio will not
|
|
break. Otherwise, leave it set. Unless you're testing what
|
|
life will be like in The Future.
