Pull char/misc/IIO/whatever driver subsystem updates from Greg KH: "Here is the 'big and hairy' char/misc/iio and other small driver subsystem updates for 6.13-rc1. Loads of things in here, and even a fun merge conflict! - rust misc driver bindings and other rust changes to make misc drivers actually possible. I think this is the tipping point, expect to see way more rust drivers going forward now that these bindings are present. Next merge window hopefully we will have pci and platform drivers working, which will fully enable almost all driver subsystems to start accepting (or at least getting) rust drivers. This is the end result of a lot of work from a lot of people, congrats to all of them for getting this far, you've proved many of us wrong in the best way possible, working code :) - IIO driver updates, too many to list individually, that subsystem keeps growing and growing... - Interconnect driver updates - nvmem driver updates - pwm driver updates - platform_driver::remove() fixups, loads of them - counter driver updates - misc driver updates (keba?) - binder driver updates and fixes - loads of other small char/misc/etc driver updates and additions, full details in the shortlog. All of these have been in linux-next for a while, with no other reported issues other than that merge conflict" * tag 'char-misc-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (401 commits) mei: vsc: Fix typo "maintstepping" -> "mainstepping" firmware: Switch back to struct platform_driver::remove() misc: isl29020: Fix the wrong format specifier scripts/tags.sh: Don't tag usages of DEFINE_MUTEX fpga: Switch back to struct platform_driver::remove() mei: vsc: Improve error logging in vsc_identify_silicon() mei: vsc: Do not re-enable interrupt from vsc_tp_reset() dt-bindings: spmi: qcom,x1e80100-spmi-pmic-arb: Add SAR2130P compatible dt-bindings: spmi: spmi-mtk-pmif: Add compatible for MT8188 spmi: pmic-arb: fix return path in for_each_available_child_of_node() iio: Move __private marking before struct element priv in struct iio_dev docs: iio: ad7380: add adaq4370-4 and adaq4380-4 iio: adc: ad7380: add support for adaq4370-4 and adaq4380-4 iio: adc: ad7380: use local dev variable to shorten long lines iio: adc: ad7380: fix oversampling formula dt-bindings: iio: adc: ad7380: add adaq4370-4 and adaq4380-4 compatible parts bus: mhi: host: pci_generic: Use pcim_iomap_region() to request and map MHI BAR bus: mhi: host: Switch trace_mhi_gen_tre fields to native endian misc: atmel-ssc: Use of_property_present() for non-boolean properties misc: keba: Add hardware dependency ...

selftests: add file SLAB_TYPESAFE_BY_RCU recycling stressor

2024-10-30T08:58:02Z

Add a simple file stressor that lives directly in-tree. This will create a bunch of processes that each open 500 file descriptors and then use close_range() to close them all. Concurrently, other processes read /proc//fd/ which rougly does f = fget_task_next(p, &fd); if (!f) break; data.mode = f->f_mode; fput(f); Which means that it'll try to get a reference to a file in another task's file descriptor table. Under heavy file load it is increasingly likely that the other task will manage to close @file and @file will be recycled due to SLAB_TYPEAFE_BY_RCU concurrently. This will trigger various warnings in the file reference counting code. Link: https://lore.kernel.org/r/20241021-vergab-streuen-924df15dceb9@brauner Signed-off-by: Christian Brauner
