+Subject: selftests: kselftest: Fix build failure with NOLIBC
+
+From: Oleg Nesterov <oleg@redhat.com>
+
+commit 16767502aa990cca2cb7d1372b31d328c4c85b40 upstream.
+
+As Mark explains ksft_min_kernel_version() can't be compiled with nolibc,
+it doesn't implement uname().
+
+Fixes: 6d029c25b71f ("selftests/timers/posix_timers: Reimplement check_timer_distribution()")
