Subject: [RFC PATCH 0/2] use gnuhash to speed up device/driver match
Date: Sat, 4 Mar 2017 08:12:41 +0100 [thread overview]
Message-ID: <20170304071241.GG4120@mail.ovh.net> (raw)
Hi,
The following patch series use the gnu hash to speedup device/driver
matching.
String compare is slow so we will calculate at runtime a hash that we
can compare quickly to speed up the match
in a second step we could speed up this more by calculating the hash
at compile time
The following changes since commit d92ed454107b4d6f0d30fa0271da191ae5911d18:
