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 option enables gcov-based code profiling (e.g. for code coverage
|
|
measurements).
|
|
|
|
If unsure, say N.
|
|
|
|
Additionally specify CONFIG_GCOV_PROFILE_ALL=y to get profiling data
|
|
for the entire kernel. To enable profiling for specific files or
|
|
directories, add a line similar to the following to the respective
|
|
Makefile:
|
|
|
|
For a single file (e.g. main.o):
|
|
GCOV_PROFILE_main.o := y
|
|
|
|
For all files in one directory:
|
|
GCOV_PROFILE := y
|
|
|
|
To exclude files from being profiled even when CONFIG_GCOV_PROFILE_ALL
|
|
is specified, use:
|
|
|
|
GCOV_PROFILE_main.o := n
|
|
and:
|
|
GCOV_PROFILE := n
|
|
|
|
Note that the debugfs filesystem has to be mounted to access
|
|
profiling data.

This options activates profiling for the entire kernel.
|
|
|
|
If unsure, say N.
|
|
|
|
Note that a kernel compiled with profiling flags will be significantly
|
|
larger and run slower. Also be sure to exclude files from profiling
|
|
which are not linked to the kernel image to prevent linker errors.
