[GIT PULL] Bootconfig: Updates for v7.0

[GIT PULL] Bootconfig: Updates for v7.0

[Masami Hiramatsu]

Hi Linus,

Bootconfig for v7.0

- Update the bootconfig parser to stop searching for a value when it
  encounters a newline character.
  Note that this changes the bootconfig formatting but this should not
  fall under the don't break user space rule as users of bootconfig is
  for booting the kernel and not about applications running in the
  kernel's user space.

- Update the tests for bootconfig parser to ensure the good examples
  to be parsed correctly by comparing the expected results.


Please pull the latest bootconfig-v7.0 tree, which can be found at:


  git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git

Note that the rule is about breaking *users*, not breaking user space per se.

It's obviously not about "user space applications", since about h alf
of the kernel is about hardware interfaces. If you break a driver, you
break the user expectations.

If some user setup breaks, things need fixing.

That said, I agree that this is not likely to break any user
configuration, but I want to make it very clear that there are no
excuses about "user space applications".

Thanks for the clarification, I'll be more careful for the rule.
