[PATCH] ftrace: set direct_ops storage-class-specifier to static
From: Tom Rix
Date: Sat Mar 11 2023 - 08:52:14 EST
smatch reports this warning
kernel/trace/ftrace.c:2594:19: warning:
symbol 'direct_ops' was not declared. Should it be static?
The variable direct_ops is only used in ftrace.c, so it should be static
