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/'

The no-op I/O scheduler is a minimal scheduler that does basic merging
|
|
and sorting. Its main uses include non-disk based block devices like
|
|
memory devices, and specialised software or hardware environments
|
|
that do their own scheduling and require only minimal assistance from
|
|
the kernel.

The deadline I/O scheduler is simple and compact. It will provide

CSCAN service with FIFO expiration of requests, switching to

a new point in the service tree and doing a batch of IO from there

in case of expiry.

The Kyber I/O scheduler is a low-overhead scheduler suitable for

multiqueue and other fast devices. Given target latencies for reads and

synchronous writes, it will self-tune queue depths to achieve that

goal.
