Revision 595a438c78dbdc43d6c9db4f437267f0bd1548bf authored by Denis Efremov on 04 July 2019, 17:21:10 UTC, committed by Steven Rostedt (VMware) on 31 August 2019, 10:51:49 UTC
The function ftrace_set_clr_event is declared static and marked EXPORT_SYMBOL_GPL(), which is at best an odd combination. Because the function was decided to be a part of API, this commit removes the static attribute and adds the declaration to the header.
