[PATCH v6 0/3] tracing/probes: allow no event name input when create group

Posted by Linyu Yuan 3 years, 10 months ago

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]

similar change apply to eprobe and uprobe.

V2: (v1: https://lore.kernel.org/lkml/1651397651-30454-1-git-send-email-quic_linyyuan@quicinc.com/)
    fix remove comment in V1 patch1,
    remove v1 patch2 as it is NACK.

v3: (v2 : https://lore.kernel.org/lkml/1653795294-19764-1-git-send-email-quic_linyyuan@quicinc.com/)
    add selftest cases for kprobe and eprobe event,
    remove macro used in v1,v2,
    change location to generate eprobe event name.

v4: (v3 : https://lore.kernel.org/lkml/1653978552-18637-1-git-send-email-quic_linyyuan@quicinc.com/)
    fix comment of kprobe/eprobe test case.

v5: (v4: https://lore.kernel.org/lkml/1654171861-24014-1-git-send-email-quic_linyyuan@quicinc.com/)
    for eprobe, when only input a "SYSTEM.", it is invalid.
    add Acked-by from Masami Hiramatsu (Google) <mhiramat@kernel.org>

v6: (v5: https://lore.kernel.org/lkml/1655168698-19898-1-git-send-email-quic_linyyuan@quicinc.com/)
    change some code order according review comment from Tom Zanussi,
    some minor changes.

Linyu Yuan (3):
  tracing: eprobe: remove duplicate is_good_name() operation
  tracing: auto generate event name when create a group of events
  selftests/ftrace: add test case for GRP/ only input
