Subject: [PATCH 0/7] char/random: Simplify random address requests
Two previous attempts have been made to rework this API. The first can be
found at:
https://lkml.kernel.org/r/cover.1390770607.git.ydroneaud@opteya.com
The second at:
https://lkml.kernel.org/r/1469471141-25669-1-git-send-email-william.c.roberts@intel.com
The RFC version of this series can been seen at:
https://lkml.kernel.org/r/20160726030201.6775-1-jason@lakedaemon.net
In addition to incorporating ideas from these two previous efforts, this series
adds several desirable features. First, we take the range as an argument
directly, which removes math both before the call and inside the function.
Second, we return the start address on error. All callers fell back to the
start address on error, so we remove the need to check for errors. Third, we
cap range to prevent overflow. Last, we use kerneldoc to describe the new
function.
If possible, I'd like to request Acks from the various subsystems so that we
can merge this as one bisectable branch.
