From: Steven Rostedt <rost...@goodmis.org> When the __vma_adjust() was converted to use the vma iterator it removed the functions vma_mas_store() and vma_mas_remove(). These functions called the tracepoints trace_vma_mas_store() and trace_vma_mas_szero() respectively. The calls to these tracepoints were removed but the trace events that created the tracepoints were not removed. Each trace event can take up to 5K of memory, and it is allocated regardless of if they are called or not.
Remove the unused trace events.
