Subject: API change - support more const arg
X-Git-Tag: v2_02_91~1097
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=2f321615f22a9fef2eaa0258d62c49212f52a8b0;p=lvm2.git

API change - support more const arg

As dm_report_field_string() doesn't modify content of data pointer,
it can be marked as const.

It's slight API change - but doesn't require any change on the user side
and supports wider range of arguments without const casting.
(i.e. we may use as paramater const lv struct this way:  &lv->name)
