From f8408264c77a0cebb20244d1f4750501b36abe0e Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 14 Jan 2021 17:05:30 +0530 Subject: drivers: Remove CONFIG_OPROFILE support The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. Remove kernel's old oprofile support.
