Subject: [PATCH 00/17] DRBD updates for 4.21
Date: Thu, 20 Dec 2018 17:23:27 +0100	[thread overview]
Message-ID: <20181220162344.8430-1-lars.ellenberg@linbit.com> (raw)


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
