Subject[PATCH 12/13] drbd: Rename --dry-run to --tentative
Date
From: Andreas Gruenbacher <agruen@linbit.com>

drbdadm already has a --dry-run option, so this option cannot directly be
passed through to drbdsetup. Rename the drbdsetup option to resolve this
conflict.

For backward compatibility, make --dry-run an alias of --tentative.
