drbd: improvements to activate/deactivate multiple activity log extents · e15766e9

Lars Ellenberg authored Apr 01, 2011

Recent commit drbd: get rid of bio_split, allow bios of "arbitrary" size
had a reference count leak: it only deactivated the first of several
activity log extents for intervals crossing extent boundaries.

This commit generalizes on bios spanning multiple activity log extents
in drbd_al_begin_io, and adds the necessary loop around lc_put in
drbd_al_complete_io as well.

Lars Ellenberg authored Mar 31, 2011

We want to avoid bio_split for bios crossing activity log boundaries.
So we may need to activate two activity log extents "atomically".
drbd_al_begin_io() needs to know more than just the start sector.

drbd: Change how the "handshake" packets are called · 6038178e

Andreas Gruenbacher authored Mar 28, 2011

Packets of type P_HAND_SHAKE define which protocol versions and features
a node supports.  For clarity, call those packets P_CONNECTION_FEATURES
instead.

(This does not determine the features that a specific drbd device
supports, such as drbd protocol A, B, C.)

drbd: Change how the initial packets are called · e5d6f33a

Andreas Gruenbacher authored Mar 28, 2011

The first packets exchanged when a connection is established are
referred to as P_HAND_SHAKE_S and P_HAND_SHAKE_M in the code, followed
by P_HAND_SHAKE packets. To avoid confusion between these two unrelated
things, call the initial packets P_INITIAL_DATA and P_INITIAL_META.
