Subject: [PATCH,bpf-next v2 0/2] Fix broken samples due to symbol mismatch

Currently, there are broken samples due to symbol mismatch (missing or
unused symbols). For example, the function open() calls the syscall 
'sys_openat' instead of 'sys_open'. And there are no exact symbols such
as 'sys_read' or 'sys_write' under kallsyms, instead the symbols have
prefixes. And these error leads to broke of samples.

This Patchset fixes the problem by changing the symbol match.

Changes in v2:
 - remove redundant casting 

Daniel T. Lee (2):
  samples: bpf: replace symbol compare of trace_event
  samples: bpf: fix syscall_tp due to unused syscall
