Subject: LVM2/lib/format_text layout.h
Date: Mon, 28 Jun 2010 20:29:00 -0000 [thread overview]
Message-ID: <20100628202942.12703.qmail@sourceware.org> (raw)
CVSROOT: /cvs/lvm2
Module name: LVM2
Changes by: wysochanski@sourceware.org 2010-06-28 20:29:42
Modified files:
lib/format_text: layout.h
Log message:
Change 'filler' to 'flags' in on-disk 'raw_locn' structure.
Future patches will make use of a specific flag in the on-disk 'raw_locn'
structure to enable/disable metadata areas, and facilitate metadata
balancing.
Note that 'filler' is always set to '0' (see add_mda() - memset),
so use of this area as a non-zero flags field is a safe way to
provide future code features.
