[dm-devel] [PATCH 0/5] Use uevent for thin pool events

[Andy Grover]

uevents both let us attach additional info to the event, and also
allow interested user processes to receive them without having to
create and manage threads to sit in DEV_WAIT ioctls for each target
we're interested in.

dm-mpath already supports generating uevents. This patchset
generalizes this code a little to allow another target to also
generate uevents, dm-thin, as a first step for what we might like to
do for all targets' events. DEV_WAIT ioctl support is unchanged.

Andy Grover (5):
  dm: Do not export dm_send_uevents
  dm: Move multipath-specific stuff out of dm-uevent.c
  dm: Inline dm_build_path_uevent into dm_path_uevent
  dm: Add uevent support for dm-thin
  dm: Update dm-uevent.txt
