drbd: use clear_bit_unlock() where appropriate · 4738fa16

Lars Ellenberg authored Feb 21, 2011

Some open-coded clear_bit(); smp_mb__after_clear_bit();
should in fact have been smp_mb__before_clear_bit(); clear_bit();

Instead, use clear_bit_unlock() to annotate the intention,
and have it do the right thing.

drbd: in drbd_suspend_al, set AL_SUSPENDED before unlocking the activity log · 61610420

Lars Ellenberg authored Feb 21, 2011

As using an empty activity log is the whole point of the excercise,
make sure it is still empty when setting AL_SUSPENDED.
