Subject: [PATCH 0/5] unconfuse get_unmapped_area and point/unpoint driver methods
Date: Tue, 10 Oct 2017 23:26:16 -0400	[thread overview]
Message-ID: <20171011032621.26979-1-nicolas.pitre@linaro.org> (raw)

This is my first MTD contribution after more than 10 years.
Feels like Back to the Future!  :-)

This series improves or implements the point and unpoint driver methods
and reimplements mtd_get_unmapped_area() in terms of those. Because
mtd->_point() provides a superset of what mtd->_get_unmapped_area() does
then there is no reason for having both. Or worse: having one but not
the other.

This is motivated by my work on XIP cramfs for both MMU and !MMU systems
where I do need the more complete point functionality. And it just looks
like the right thing to do. Existing users won't see a difference.
