Subject: [PATCH v6 6/8] block: bio: remove BIO_MAX_SECTORS
Date: Mon, 30 May 2016 21:34:34 +0800	[thread overview]
Message-ID: <1464615294-9946-7-git-send-email-ming.lei@canonical.com> (raw)
In-Reply-To: <1464615294-9946-1-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.
