Subject: Re: [PATCH 09/16] sparc64: use the generic get_user_pages_fast code
Date: Sat, 10 Aug 2019 21:36:26 +0200 [thread overview]
Message-ID: <CAM43=SNbjVJRZs7r=GqFG0ajOs5wY4pZzr_QfVZinFRWV8ioBg@mail.gmail.com> (raw)

For the record the futex test case OOPSes a 5.3-rc3 kernel running on
a Sun Blade 2500 (2 x USIIIi). This system runs a custom distro with
a custom toolchain (gcc-8.3 based), so I doubt it's a distro problem.
