lru_cache: allow multiple changes per transaction · 46a15bc3

Lars Ellenberg authored Feb 21, 2011

Allow multiple changes to the active set of elements in lru_cache.
The only current user of lru_cache, drbd, is driving this generalisation.

drbd: allow to select specific bitmap pages for writeout · 45dfffeb

Lars Ellenberg authored Feb 21, 2011

We are about to allow several changes to the active set in one activity
log transaction. We have to write out the corresponding bitmap pages as
well, if changed.

Introduce drbd_bm_mark_for_writeout(), then re-use the existing bitmap
writeout path to submit all marked pages in one go.

lru_cache.h: fix comments referring to ts_ instead of lc_ · 0097f040

Lars Ellenberg authored Feb 21, 2011

For some time we contemplated calling the "struct lru_cache"
a "struct tracked_set", and some comments kept the ts_ prefix.

Fix those to match the member field names.

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.
