  "message": "ptrace: kill trivial tracehooks\n\nAt this point, tracehooks aren\u0027t useful to mainline kernel and mostly\njust add an extra layer of obfuscation.  Although they have comments,\nwithout actual in-kernel users, it is difficult to tell what are their\nassumptions and they\u0027re actually trying to achieve.  To mainline\nkernel, they just aren\u0027t worth keeping around.\n\nThis patch kills the following trivial tracehooks.\n\n* Ones testing whether task is ptraced.  Replace with -\u003eptrace test.\n\n\ttracehook_expect_breakpoints()\n\ttracehook_consider_ignored_signal()\n\ttracehook_consider_fatal_signal()\n\n* ptrace_event() wrappers.  Call directly.\n\n\ttracehook_report_exec()\n\ttracehook_report_exit()\n\ttracehook_report_vfork_done()\n\n* ptrace_release_task() wrapper.  Call directly.\n\n\ttracehook_finish_release_task()\n\n* noop\n\n\ttracehook_prepare_release_task()\n\ttracehook_report_death()\n\nThis doesn\u0027t introduce any behavior change.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\n",
