| H A D | data-convert-bt.c | e0a7cce5 Sat Apr 18 10:50:19 CDT 2015 Wang Nan <wangnan0@huawei.com> perf data: Fix duplicate field names and avoid reserved keywords
Some parameters of syscall tracepoints named as 'nr', 'event', etc.
When dealing with them, perf convert to ctf meets some problem:
1. If a parameter with name 'nr', it will duplicate syscall's
common field 'nr'. One such syscall is io_submit().
2. If a parameter with name 'event', it is denied to be inserted
because 'event' is a CTF spec keyword[1]. One such syscall is
epoll_ctl.
This patch appends '_dupl_X' suffix to avoid problem 1, prepend a '_'
prefix to avoid problem 2.
