[PATCH 10/30] clocksource/drivers/arm_arch_timer: Use kstrtobool() instead of strtobool()

[PATCH 10/30] clocksource/drivers/arm_arch_timer: Use kstrtobool() instead of strtobool()

[Christophe JAILLET]

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>)

Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

This patch is part of a serie that axes all usages of strtobool().
Each patch can be applied independently from the other ones.

The last patch of the serie removes the definition of strtobool().

You may not be in copy of the cover letter. So, if needed, it is available
at [1].

Hi,

This has been A-b 2 months ago, and I've just resent patches in this 
serie that have neither been merged in -next, nor A-b or R-b.

So for this one, it is just a polite reminder. :)

Do you have visibility on when it should be merged?

CJ

When large tree-wide series turn up on the list, there's always a
confusion on how they'd get merged. I guess you are expecting such
patches to go in via individual maintainer trees. It wasn't obvious from
to me (I can now see there was some text in the patch description).

I'll add it to my list for 6.3.
