Subject: [PATCH 8/9] msgmap: ->new_file to supports $ibx arg, drop ->new
Date: Tue, 12 Oct 2021 11:47:04 +0000	[thread overview]
Message-ID: <20211012114705.383-9-e@80x24.org> (raw)
In-Reply-To: <20211012114705.383-1-e@80x24.org>

The original Msgmap->new API was v1-specific and not necessary.
The ->new_file API now supports an $ibx object being passed to
it, simplify -no_fsync use.  It will also make an upcoming
change easier...
