2014-07-10drbd: application writes may set-in-sync in protocol != CLars Ellenberg1-1/+3
If "dirty" blocks are written to during resync, that brings them in-sync. By explicitly requesting write-acks during resync even in protocol != C, we now can actually respect this. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

2011-09-28drbd: _req_conflicts(): Get rid of the epoch_entries treeAndreas Gruenbacher1-0/+1
Instead of keeping a separate tree for local and remote write requests for finding requests and for conflict detection, use the same tree for both purposes. Introduce a flag to allow distinguishing the two possible types of entries in this tree.
