Hi Jens, I hope this is not too late for your for-4.21 branch. These are all from last April or even older, I was convinced we sent these for 4.19 already. But we didn't :-( The interesting new feature is "introduce P_ZEROES", which is replacing 45c21793a660 drbd: implement REQ_OP_WRITE_ZEROES because that led to "full allocation" for fstrim on dm-thin or similar, which is certainly not the intended behavior. Patch 3 to 8 help with recovery from odd corner cases in multiple error scenarios in a cluster, potentially after some admin already "tried things". All others are sufficiently simple and supposedly "obvious". Lars Ellenberg (13): drbd: must not use connection after kref_put(&connection->kref) drbd: centralize printk reporting of new size into drbd_set_my_capacity() drbd: ignore "all zero" peer volume sizes in handshake drbd: disconnect, if the wrong UUIDs are attached on a connected peer drbd: fix confusing error message during attach drbd: attach on connected diskless peer must not shrink a consistent device drbd: reject attach of unsuitable uuids even if connected drbd: fix comment typos drbd: do not block when adjusting "disk-options" while IO is frozen drbd: avoid spurious self-outdating with concurrent disconnect / down drbd: don't retry connection if peers do not agree on "authentication" settings drbd: skip spurious timeout (ping-timeo) when failing promote drbd: introduce P_ZEROES (REQ_OP_WRITE_ZEROES on the "wire") Luc Van Oostenryck (1): drbd: fix print_st_err()'s prototype to match the definition Nathan Chancellor (2): drbd: Avoid Clang warning about pointless switch statment drbd: Change drbd_request_detach_interruptible's return type to int Roland Kammerer (1): drbd: narrow rcu_read_lock in drbd_sync_handshake drivers/block/drbd/drbd_debugfs.c | 2 + drivers/block/drbd/drbd_int.h | 19 +-- drivers/block/drbd/drbd_main.c | 28 +++- drivers/block/drbd/drbd_nl.c | 133 ++++++++++++--- drivers/block/drbd/drbd_protocol.h | 47 ++++++ drivers/block/drbd/drbd_receiver.c | 251 +++++++++++++++++++++++++---- drivers/block/drbd/drbd_req.c | 19 +-- drivers/block/drbd/drbd_req.h | 2 + drivers/block/drbd/drbd_state.c | 11 +- drivers/block/drbd/drbd_state.h | 5 +- drivers/block/drbd/drbd_worker.c | 2 +- include/linux/drbd.h | 2 +- include/linux/genl_magic_struct.h | 5 +- 13 files changed, 434 insertions(+), 92 deletions(-) -- 2.17.1
