X-Git-Url: http://git.vrable.net/?a=commitdiff_plain;ds=sidebyside;h=2f883084c4393dc7b730df2e778b9f2fc14f70e0;hp=2f883084c4393dc7b730df2e778b9f2fc14f70e0;p=bluesky.git

Allow cleaner to delete unused log segments.

It will not delete segments cleaned out in the current pass, just those
that were unreferenced at the start of the cleaning process.
