[GIT PULL] Kselftest update for 4.12-rc1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

Please pull the following update for 4.12-rc1

This update consists of:

-- important fixes for build failures and clean target related warnings
   to address regressions introduced in:
   88baa78d1f31 ("selftests: remove duplicated all and clean target")

-- several minor spelling fixes in and log messages and comment blocks.

-- Enabling configs for better test coverage in ftrace, vm, cpufreq tests.

-- .gitignore changes


Stephen saw a conflict during linux-next merge of the akpm-current tree

between commit:

  ff80d9152fd7 ("selftests/vm/run_vmtests: Fix wrong comment")

from the kselftest tree and commit:

  7b7c7dac4437 ("userfaultfd: selftest: combine all cases into a single executable")

Stephen fixed this up in linux-next and volunteered to carry forward
the fix - fix diff attached. Please let me know if this isn't acceptable.
Sorry for the inconvenience.

Diff for the update attached.

thanks,
-- Shuah
