Subject[PATCH 00/12] samples: configfs: refactor the configfs sample code
From: Bartosz Golaszewski <>

Over at the GPIO sub-system we have a testing module (gpio-mockup) which
uses module params to instantiate simulated GPIO chips and debugfs to
control them. We want to switch to a more stable interface using configfs
to instantiate chips and sysfs to control them.

For that we need the feature that's well defined in the docs but currently
unimplemented - committable items. I started working on this but it won't
be ready for this release cycle.

In the meantime I also refactored the configfs samples a bit as I'll be
adding sample code for committable items. I thought that it won't hurt
to send the refactoring patches now for v5.10 so here it is. No logical
changes really, mostly just code quality and removing usage of deprecated

Bartosz Golaszewski (12):
MAINTAINERS: add the sample directory to the configfs entry
samples: configfs: order includes alphabetically
samples: configfs: remove redundant newlines
samples: configfs: drop unnecessary ternary operators

samples: configfs: replace simple_strtoul() with kstrtoint()
samples: configfs: don't reinitialize variables which are already
samples: configfs: prefer sizeof(*var) to sizeof(struct var_type)
samples: configfs: consolidate local variables of the same type
samples: configfs: don't use spaces before tabs
