Apart from the usual maintenance and bug fixes this time comes support for WRITE_SAME and lots of improvements for DISCARD. At that time we had a discussion about (1) the all_zero() heuristic introduced with [PATCH 04/30] drbd: Implement handling of thinly provisioned storage... not being efficient, and about the (2) rs-discard-granularity configuration parameter. Regarding (1): I intend to work on block-devices being able to export their allocation map by either FIEMAP or SEEK_HOLE/SEEK_DATA or both for the next cycle. The I will change DRBD to use that as well. Regarding (2): We need to announce the discard granularity when we create the device/minor. At might it might be that there is no connection to the peer node. So we are left with information about the discard granularity of the local backing device only. Therefore we decided to delegate it to the user/admin to provide the discard granularity for the resync process. Please add it to your for-4.8/drivers branch. Thanks! Fabian Frederick (1): drbd: code cleanups without semantic changes Lars Ellenberg (24): drbd: bitmap bulk IO: do not always suspend IO drbd: change bitmap write-out when leaving resync states drbd: adjust assert in w_bitmap_io to account for BM_LOCKED_CHANGE_ALLOWED drbd: fix regression: protocol A sometimes synchronous, C sometimes double-latency drbd: fix for truncated minor number in callback command line drbd: allow parallel flushes for multi-volume resources drbd: when receiving P_TRIM, zero-out partial unaligned chunks drbd: possibly disable discard support, if backend has discard_zeroes_data=0 drbd: zero-out partial unaligned discards on local backend drbd: allow larger max_discard_sectors drbd: finish resync on sync source only by notification from sync target drbd: introduce unfence-peer handler drbd: don't forget error completion when "unsuspending" IO drbd: if there is no good data accessible, writes should be IO errors drbd: only restart frozen disk io when D_UP_TO_DATE drbd: discard_zeroes_if_aligned allows "thin" resync for discard_zeroes_data=0 drbd: report sizes if rejecting too small peer disk drbd: introduce WRITE_SAME support drbd: sync_handshake: handle identical uuids with current (frozen) Primary drbd: disallow promotion during resync handshake, avoid deadlock and hard reset drbd: bump current uuid when resuming IO with diskless peer drbd: finally report ms, not jiffies, in log message drbd: al_write_transaction: skip re-scanning of bitmap page pointer array drbd: correctly handle failed crypto_alloc_hash Philipp Reisner (4): drbd: Kill code duplication drbd: Implement handling of thinly provisioned storage on resync target nodes drbd: Introduce new disk config option rs-discard-granularity drbd: Create the protocol feature THIN_RESYNC Roland Kammerer (1): drbd: get rid of empty statement in is_valid_state drivers/block/drbd/drbd_actlog.c | 29 +- drivers/block/drbd/drbd_bitmap.c | 84 ++++-- drivers/block/drbd/drbd_debugfs.c | 13 +- drivers/block/drbd/drbd_int.h | 49 +++- drivers/block/drbd/drbd_interval.h | 14 +- drivers/block/drbd/drbd_main.c | 115 +++++++- drivers/block/drbd/drbd_nl.c | 282 +++++++++++++++----- drivers/block/drbd/drbd_proc.c | 30 +-- drivers/block/drbd/drbd_protocol.h | 77 +++++- drivers/block/drbd/drbd_receiver.c | 534 ++++++++++++++++++++++++++++++------- drivers/block/drbd/drbd_req.c | 84 ++++-- drivers/block/drbd/drbd_req.h | 5 +- drivers/block/drbd/drbd_state.c | 61 ++++- drivers/block/drbd/drbd_state.h | 2 +- drivers/block/drbd/drbd_strings.c | 8 +- drivers/block/drbd/drbd_worker.c | 85 +++++- include/linux/drbd.h | 10 +- include/linux/drbd_genl.h | 7 +- include/linux/drbd_limits.h | 15 +- 19 files changed, 1205 insertions(+), 299 deletions(-) -- 2.7.4
