The patch titled
Subject: parse_integer: convert mm/
has been removed from the -mm tree. Its filename was
parse_integer-convert-mm.patch
This patch was dropped because it was nacked
------------------------------------------------------
From: Alexey Dobriyan <adobriyan@xxxxxxxxx>
Subject: parse_integer: convert mm/
Convert mm/ directory away from deprecated simple_strto*() interface.
One thing to note about parse_integer() and seemingly useless casts --
range of accepted values depends on result type.
int val;
parse_integer(s, 0, &val);
will accept negative integers, while
int val;
parse_integer(s, 0, (unsigned int *)&val);
will accept only 0 and positive integers.
Cast is needed when result variable has to be of different type
for some reason.
This is very important and hopefully [knocks wood] obvious.
