For many usages, we want to preserve the # "const" attribute by using the same call. For a specific example, this # series changes the kobj_to_dev() macro to use it, allowing it to be # used no matter what the const value is. This prevents every subsystem # from having to declare 2 different individual macros (i.e. # kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce # the const value at build time, which having 2 macros would not do # either. # # The driver for all of this have been discussions with the Rust kernel # developers as to how to properly mark driver core, and kobject, # objects as being "non-mutable". The changes to the kobject and driver # core in this pull request are the result of that, as there are lots of # paths where kobjects and device pointers are not modified at all, so # marking them as "const" allows the compiler to enforce this. # # So, a nice side affect of the Rust development effort has been already # to clean up the driver core code to be more obvious about object # rules. # # All of this has been bike-shedded in quite a lot of detail on lkml # with different names and implementations resulting in the tiny version # we have in here, much better than my original proposal. Lots of # subsystem maintainers have acked the changes as well. # # Other than this change, included in here are smaller stuff like: # # - kernfs fixes and updates to handle lock contention better # # - vmlinux.lds.h fixes and updates # # - sysfs and debugfs documentation updates # # - device property updates # # All of these have been in the linux-next tree for quite a while with # no problems" # # tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) # device property: Fix documentation for fwnode_get_next_parent() # firmware_loader: fix up to_fw_sysfs() to preserve const # usb.h: take advantage of container_of_const() # device.h: move kobj_to_dev() to use container_of_const() # container_of: add container_of_const() that preserves const-ness of the pointer # driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. # driver core: fix up missed scsi/cxlflash class.devnode() conversion. # driver core: fix up some missing class.devnode() conversions. # driver core: make struct class.devnode() take a const * # driver core: make struct class.dev_uevent() take a const * # cacheinfo: Remove of_node_put() for fw_token # device property: Add a blank line in Kconfig of tests # device property: Rename goto label to be more precise # device property: Move PROPERTY_ENTRY_BOOL() a bit down # device property: Get rid of __PROPERTY_ENTRY_ARRAY_ELSIZE() # kernfs: fix all kernel-doc warnings and multiple typos # driver core: pass a const * into of_device_uevent() # kobject: kset_uevent_ops: make name() callback take a const * # kobject: kset_uevent_ops: make filter() callback take a const * # kobject: make kobject_namespace take a const * # ... # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 71a7507afbc3f27c346898f13ab9bfd918613c34 # < make -s -j 160 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 160 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 160 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 160 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/drivers/gpu/drm/../../accel/drm_accel.c: In function 'accel_sysfs_init': /kisskb/src/drivers/gpu/drm/../../accel/drm_accel.c:41:23: error: assignment to 'char * ()(const struct device , umode_t )' {aka 'char ()(const struct device , short unsigned int )'} from incompatible pointer type 'char ()(struct device , umode_t )' {aka 'char ()(struct device , short unsigned int )'} [-Werror=incompatible-pointer-types] accel_class->devnode = accel_devnode; ^ cc1: all warnings being treated as errors make[5]: [/kisskb/src/scripts/Makefile.build:250: drivers/gpu/drm/../../accel/drm_accel.o] Error 1 make[5]: * Waiting for unfinished jobs.... make[4]: * [/kisskb/src/scripts/Makefile.build:502: drivers/gpu/drm] Error 2 make[3]: * [/kisskb/src/scripts/Makefile.build:502: drivers/gpu] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:502: drivers] Error 2 make[1]: * [/kisskb/src/Makefile:1994: .] Error 2 make: *** [Makefile:231: __sub-make] Error 2 Command 'make -s -j 160 ARCH=x86 O=/kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/x86_64-linux/bin/x86_64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_x86-allmodconfig_x86_64-gcc8 # Build took: 0:12:12.809986
