Subject: [PATCH v7 1/2] x86/resctrl: Rename pseudo_lock_event.h to trace.h
Date: Mon,  8 Apr 2024 17:23:02 +0800

Now only pseudo-locking part uses tracepoints to do event tracking, but
other parts of resctrl may need new tracepoints. It is unnecessary to
create separate header files and define CREATE_TRACE_POINTS in different
c files which fragments the resctrl tracing.

Therefore, give the resctrl tracepoint header file a generic name to
support its use for tracepoints that are not specific to pseudo-locking.

No functional change.
