Subject: Re: [PATCH v2 3/7] block: refactor iov_count_pages() from bio_{copy,map}_user_iov()
Date: Fri, 16 Jan 2015 03:41:46 -0800	[thread overview]
Message-ID: <20150116114146.GA31449@infradead.org> (raw)
In-Reply-To: <0117035a25929ae97e2039edc895f582d53cf217.1421052656.git.dongsu.park@profitbricks.com>

mm/iov_iter.c already has a iov_iter_npages, although that
one doesn't do an alignment check yet.  But it might be worth
to just the iov_iter_alignment similar to how iov_iter_alignment
does it instead of this new function.
