Subject: rbd: kill rbd_image_header->snap_seq
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=9e15dc735a7a0418be14e2deab44ddee369af857;p=~shefty%2Frdma-dev.git

rbd: kill rbd_image_header->snap_seq

The snap_seq field in an rbd_image_header structure held the value
from the rbd image header when it was last refreshed.  We now
maintain this value in the snapc->seq field.  So get rid of the
other one.
