The conversion from strtobool() to kstrtobool() is completed.
So strtobool() can now be removed.

Unless I missed something, the last strtobool() calls have been removed
from -next just 1 or 2 days ago.

So it is maybe good to wait a few days or weeks to apply this patch in
order not to break something somewhere.

For now, see if build-bots agree with me :)


get_maintainer.pl is of now help here, so adding just Andrew Morton, and
Andy Shevchenko (who splitted out this file from kernel.h)

I still have some strtobool()s in mm.git, so I can't apply this. 

Probably nobody can apply this to their tree at this stage.  A resend
after 6.6-rc1 would be the simplest approach.

Let's do it then.

Note that in -next there is still some strtobool but only in tools/.
I thinks it is ok to leave it as-is.


git grep -w strtobool

tools/include/linux/string.h:int strtobool(const char *s, bool *res);
tools/lib/string.c: *  More specifically, the first copied function was 
strtobool, which

semantics of existing in kernel equivalents")
tools/lib/string.c: * strtobool - convert common user inputs into

tools/lib/string.c:int strtobool(const char *s, bool *res)
tools/perf/util/bpf-loader.c:   err = strtobool(value, &bool_value);

Kees Cook from recent times.

As this is about Linux Next, you need to talk to Torvalds to apply this before
v6.6-rc1.

Code wise it's good, feel free to add:
