Subject: [PATCH v1 6/8] block: bio: remove BIO_MAX_SECTORS
Date: Thu, 31 Mar 2016 00:17:15 +0800 [thread overview]
Message-ID: <1459354637-17415-7-git-send-email-ming.lei@canonical.com> (raw)
In-Reply-To: <1459354637-17415-1-git-send-email-ming.lei@canonical.com>
No one need this macro, so remove it. The motivation is
for supporting multipage bvecs, in which we only know
what the max count of bvecs is supported in the bio,
instead of max size or max sectors.
