Hey,
The first patch in this series is a fix for another race issue with
the test infrastructure.
The remaining 4 patches address Christoph's feedback in my previous
patchset that I sent rather late in the cycle. (Sorry about that).
This series is based on current md-next (ae0a80935d6a6).

externs should not be used in function declarations, so clean those
up.

The atomic_read() is not needed in many cases so only do
the read after the first checks are done.

2.30.2
From: David Sloan <[email protected]>
A race condition still exists when removing and re-creating md devices
in test cases. However, it is only seen on some setups.
The race condition was tracked down to a reference still being held
to the kobject by the rdev in the md_rdev_misc_wq which will be released
in rdev_delayed_delete().
md_alloc() waits for previous deletions by waiting on the md_misc_wq,
but the md_rdev_misc_wq may still be holding a reference to a recently
removed device.
To fix this, also flush the md_rdev_misc_wq in md_alloc().

Drop the three bools in the prototype of raid5_get_active_stripe()
and replace them with a flags parameter.
At the same time, drop the distinction with __raid5_get_active_stripe().

The series looks fine to me, but all except for patch 1 really
is 6.1 material.
