percpu_counter: add debugobj support

All percpu counters are linked to a global list on initialization and
removed from it on destruction.  The list is walked during CPU up/down.
If a percpu counter is freed without being properly destroyed, the system
will oops only on the next CPU up/down making it pretty nasty to track
down.  This patch adds debugobj support for percpu counters so that such
problems can be found easily.

As percpu counters don't make sense on stack and can't be statically
initialized, debugobj support is pretty simple.  It's initialized and
activated on counter initialization, and deactivatd and destroyed on
counter destruction.  With this patch applied, the bug fixed by commit
602586a83b719df0fbd94196a1359ed35aeb2df3 (shmem: put_super must

14 years agoscripts/get_maintainer.pl: add interactive mode

scripts/get_maintainer.pl: add interactive mode

This is a first version of an interactive mode for
scripts/get_maintainer.pl.

It allows the user to interact with the script.  Each cc candidate can be
selected and deselected and a shortlog of authored commits can be
displayed for each candidate.

The menu is displayed via STDERR, the end result is outputted to STDOUT.
This unusual mechanism allows using get_maintainer.pl in interactive mode
via git send-email --cc-cmd.

Sure.

Add a search path for the .conf file.

3 paths are added:

.             customized per-tree configurations
$HOME         user global configuration when per-tree configs don't exist
./scripts     lk defaults to override script

14 years agoscripts/get_maintainer.pl: add default --git-fallback, remove default --git
Joe Perches [Tue, 26 Oct 2010 21:22:53 +0000 (14:22 -0700)]
scripts/get_maintainer.pl: add default --git-fallback, remove default --git

Adding commit signers when there is a listed MAINTAINER for a file
can make the output list longer than necessary.

Change the --git default from on to off.

Add a new --git-fallback option (default on) used to add commit signers
only when there is no MAINTAINER for a file.

git history is used when --git-fallback is enabled and the pattern
directory depth is not the same as the file directory depth.

For instance:

X86 ARCHITECTURE (32-BIT AND 64-BIT)
M: Thomas Gleixner <tglx@linutronix.de>
M: Ingo Molnar <mingo@redhat.com>
M: "H. Peter Anvin" <hpa@zytor.com>
M: x86@kernel.org
T: git git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git
S: Maintained
F: Documentation/x86/
F: arch/x86/

If using "./scripts/get_maintainer -f arch/x86/lib/atomic64_32.c", the pattern
for "arch/x86/" does not match the directory depth of "arch/x86/lib"
so the MAINTAINERS entries and git history is used to produce:

$ ./scripts/get_maintainer.pl -f --rolestats arch/x86/lib/atomic64_32.c
Thomas Gleixner <tglx@linutronix.de> (maintainer:X86 ARCHITECTURE...)
Ingo Molnar <mingo@redhat.com> (maintainer:X86 ARCHITECTURE...)
"H. Peter Anvin" <hpa@zytor.com> (maintainer:X86 ARCHITECTURE...,commit_signer:1/1=100%)
x86@kernel.org (maintainer:X86 ARCHITECTURE...)
Luca Barbieri <luca@luca-barbieri.com> (commit_signer:1/1=100%)
linux-kernel@vger.kernel.org (open list)

Luca Barbieri is added because he signed the only commit to
arch/x86/lib/atomic64_32.c during the last year and he meets the
other default qualifications.
--git-min-percent (default:10)
--git-min-signatures (default:1)

If current users of ./scripts/get_maintainers.pl have scripts
that use --nogit that expect git history to be excluded, those
scripts should be updated to include --nogit-fallback or a
.get_maintainer.conf file should be created with --nogit-fallback.
