Subject: [PATCH 20/32] read-cache: mark updated entries for split index
Date: Mon, 28 Apr 2014 17:55:41 +0700 [thread overview]
Message-ID: <1398682553-11634-21-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1398682553-11634-1-git-send-email-pclouds@gmail.com>
The large part of this patch just follows CE_ENTRY_CHANGED
marks. replace_index_entry() is updated to update
split_index->base->cache[] as well so base->cache[] does not reference
to a freed entry.
