Subject: [PATCH v6 1/2] x86/resctrl: Rename pseudo_lock_event.h to trace.h
Date: Tue, 19 Mar 2024 16:30:38 +0800 [thread overview]
Message-ID: <20240319083039.223088-2-haifeng.xu@shopee.com> (raw)
In-Reply-To: <20240319083039.223088-1-haifeng.xu@shopee.com>
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.
