The usermode helper declarations were previously provided by linux/kmod.h but commit c1f3fa2a4fde ("kmod: split off umh headers into its own file") moved them to linux/umh.h in 2017. Add explicit includes of linux/umh.h to files that use usermode helpers and remove linux/kmod.h where it is no longer needed.
Also add a missing include of linux/sysctl.h to kernel/time/jiffies.c.
Finally, clean up linux/kmod.h so that it includes only the headers that it actually requires, importantly removing the compat linux/umh.h include.
This cleanup is motivated by trying to reduce the preprocessed size of linux/module.h, which includes linux/kmod.h. The linux/module.h header is included by every *.mod.c file to provide `struct module` and other related definitions, so it should avoid pulling in unnecessary dependencies. Note that this series doesn't immediately improve the situation, since most of the files included by linux/kmod.h are, for now, also included by linux/module.h through other paths.
Apologies for the wide distribution. Acked-bys are appreciated.
Changes in v2: - Remove the linux/kmod.h include from kernel/cgroup/cgroup-v1.c. - Add a missing include of linux/sysctl.h to kernel/time/jiffies.c. - Link to v1: https://lore.kernel.org/linux-modules/20260708154510.6794-1-petr.pavlu@suse....
Petr Pavlu (3): umh, treewide: Explicitly include linux/umh.h where needed time/jiffies: Include linux/sysctl.h for proc_int_u2k_conv_uop(), ... module: Bring includes in linux/kmod.h up to date
