Subject: [PATCH 07/17] md: raid1/raid10: don't use .bi_vcnt to check if all pages are added
Date: Thu, 16 Feb 2017 19:45:37 +0800 [thread overview]
Message-ID: <1487245547-24384-8-git-send-email-tom.leiming@gmail.com> (raw)
In-Reply-To: <1487245547-24384-1-git-send-email-tom.leiming@gmail.com>
Instead we use the index of the pre-allocated pages buffer, it should
be more explicit because the index(.bi_error) just means how many pages
are added to the bio.
