[lvm-devel] [PATCH 0/3] shared snapshot removal fix and cleanups

[Mike Snitzer]

Mikulas,

These patches apply at the end of the quilt series I published here:
http://people.redhat.com/msnitzer/patches/multisnap/lvm2/LVM2-2.02.62/

Please make sure you have udev_sync enabled when testing; otherwise
the shared exception store (-cow and -real) device removal will be
unreliable (racing with udev).

Mike Snitzer (3):
  Use the origin's uuid as the basis for the shared cow's uuid.
  Introduce find_shared_cow() and lv_is_shared_cow() wrappers.
  Eliminate 'shared_snapshot' from 'struct logical_volume'.
