Since commit 84af7a6194e4 ("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/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

If you say Y here, then your Linux box will be able to act as a
|
|
DANH ("Doubly attached node implementing HSR"). For this to work,
|
|
your Linux box needs (at least) two physical Ethernet interfaces,
|
|
and it must be connected as a node in a ring network together with
|
|
other HSR capable nodes.
|
|
|
|
All Ethernet frames sent over the hsr device will be sent in both
|
|
directions on the ring (over both slave ports), giving a redundant,
|
|
instant fail-over network. Each HSR node in the ring acts like a
|
|
bridge for HSR frames, but filters frames that have been forwarded
|
|
earlier.
|
|
|
|
This code is a "best effort" to comply with the HSR standard as
|
|
described in IEC 62439-3:2010 (HSRv0) and IEC 62439-3:2012 (HSRv1),
|
|
but no compliancy tests have been made. Use iproute2 to select
|
|
the version you desire.
|
|
|
|
You need to perform any and all necessary tests yourself before
|
|
relying on this code in a safety critical system!
|
|
|
|
If unsure, say N.
