[PATCH v4 0/3] tracing/probes: allow no event name input when create group
From: Linyu Yuan
Date: Thu Jun 02 2022 - 08:11:15 EST
take kprobe event as example, when create a group of events,
p[:[GRP/]EVENT] [MOD:]KSYM[+OFFS]|KADDR [FETCHARGS],
according to this format, we must input EVENT name,
this change allow only GRP/ input, EVENT name auto generate from KSYM,
p[:[GRP/][EVENT]] [MOD:]KSYM[+OFFS]|KADDR [FETCHARGS]
siliar change apply to eprobe and uprobe.
V1: https://lore.kernel.org/lkml/1651397651-30454-1-git-send-email-quic_linyyuan@xxxxxxxxxxx/

v3: (v2 link: https://lore.kernel.org/lkml/1653795294-19764-1-git-send-email-quic_linyyuan@xxxxxxxxxxx/)
add selftest cases for kprobe and eprobe event,
remove macro used in v1,v2,
change location to generate eprobe event name.
v4: (v3 link: https://lore.kernel.org/lkml/1653978552-18637-1-git-send-email-quic_linyyuan@xxxxxxxxxxx/)
fix comment of kprobe/eprobe test case.
