Add an imperfect option to search a source file for email addresses.
New option: --file-emails or --fe
email addresses in files are freeform text and are nearly impossible to
parse. Still, might as well try to do a somewhat acceptable job of
finding them. This code should find all addresses that are in the form
addr@domain.tld
The code assumes that up to 3 alphabetic words along with dashes, commas,
and periods that preceed the email address are a name.
If 3 words are found for the name, and one of the first two words are a
single letter and period, or just a single letter then the 3 words are use
as name otherwise the last 2 words are used.
Some variants that are shown correctly:
John Smith <jksmith@domain.org>
Random J. Developer <rjd@tld.com>
Random J. Developer (rjd@tld.com)
J. Random Developer rjd@tld.com
Variants that are shown nominally correctly:
Written by First Last (funny-addr@somecompany.com)
is shown as:
First Last <funny-addr@somecompany.com>
Variants that are shown incorrectly:
Some Really Long Name <srln@foo.bar>
MontaVista Software, Inc. <source@mvista.com>
are returned as:
Long Name <srln@foo.bar>
"Software, Inc" <source@mvista.com>
--roles and --rolestats show "(in file)" for matches.
For instance:
Without -file-emails:
$ ./scripts/get_maintainer.pl -f -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])
linux-kernel@vger.kernel.org (open list)
With -fe:
$ ./scripts/get_maintainer.pl -f -fe -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])
Matt Mackall <mpm@selenic.com> (in file)
Ingo Molnar <mingo@redhat.com> (in file)
linux-kernel@vger.kernel.org (open list)
netdev@vger.kernel.org (open list:NETWORKING [GENERAL])
The number of email addresses in the file in not limited. Neither is the
number of returned email addresses.

tasklist_lock does protect the task and its pid, it can't go away. The
problem is that find_pid_ns() itself is unsafe without rcu lock, it can
race with copy_process()->free_pid(any_pid).
Protecting copy_process()->free_pid(any_pid) with tasklist_lock would make
it possible to call find_task_by_pid_ns() under tasklist safely, but we
don't do so because we are trying to get rid of the read_lock sites of
tasklist_lock.

I've had some complaints about panic_timeout being wildly innacurate on
shared processor PowerPC partitions (a 3 minute panic_timeout taking 30
minutes).
The problem is we loop on mdelay(1) and with a 1ms in 10ms hypervisor
timeslice each of these will take 10ms (ie 10x) longer. I expect other
platforms with shared processor hypervisors will see the same issue.
This patch keeps the old behaviour if we have a panic_blink (only keyboard
LEDs right now) and does 1 second mdelays if we don't.

Make sure compiler won't do weird things with limits. E.g. fetching them
twice may return 2 different values after writable limits are implemented.
I.e. either use rlimit helpers added in commit 3e10e716ab ("resource:
add helpers for fetching rlimits") or ACCESS_ONCE if not applicable.

Add adds a debugfs interface and additional failure modes to LKDTM to
provide similar functionality to the provoke-crash driver submitted here:
http://lwn.net/Articles/371208/
Crashes can now be induced either through module parameters (as before)
or through the debugfs interface as in provoke-crash.
The patch also provides a new "direct" interface, where KPROBES are not
used, i.e., the crash is invoked directly upon write to the debugfs
file. When built without KPROBES configured, only this mode is available.

The only in tree external users of the symbol setup_max_cpus are in
arch/x86/. The files ./kernel/alternative.c, ./kernel/visws_quirks.c, and
./mm/kmemcheck/kmemcheck.c are all guarded by CONFIG_SMP being defined.
For this case the symbol is an unsigned int and declared as an extern in
include/linux/smp.h.
When CONFIG_SMP is not defined the symbol setup_max_cpus is
a constant value that is only used in init/main.c. Make the symbol
static for this case.

Dependent on CONFIG_SMP the num_*_cpus() functions return unsigned or
signed values. Let them always return unsigned values to avoid strange
casts.
Fixes at least one warning:
