Like machine__findnew_module_dso(), it should set necessary info for
kernel modules to find symbol info from the file. Factor out
dso__set_module_info() to do it.
This is needed for dso__needs_decompress() to detect such DSOs.

Change it to show a warning only if failed to parse the given token as
any of valid parameter. Also code under try_numbers requires the token
to be a number, it's good to show the warning there.

The function-fork option is same as event-fork that it tracks task
fork/exit and set the pid filter properly. This can be useful if user
wants to trace selected tasks including their children only.

ftrace: Fix function pid filter on instances
ftrace: Add 'function-fork' trace option
selftests: ftrace: Add -l/--logdir option
selftests: ftrace: Add a testcase for function PID filter
kernel/trace/ftrace.c
The function-fork option is same as event-fork that it tracks task
fork/exit and set the pid filter properly. This can be useful if user
wants to trace selected tasks including their children only.

In my virtual machine setup, running ftracetest failed on creating
LOG_DIR on a read-only filesystem. It'd be convenient to provide an
option to specify a different directory as log directory.

The -q/--quiet option is to suppress any message. Sometimes users just
want to run the command and it can be used for that case.

But in that case, using pstore will crash the kernel anyway, right?
If so, why pstore doesn't keep a

There are many open calls to fprintf() for error logging. use pr_err()
instead so that they can be treated at once (e.g. with -q option).
Also convert perror() to pr_err() + str_error_r().
