[PATCH 1/2] umh, treewide: Explicitly include linux/umh.h where needed

Petr Pavlu petr.pavlu at suse.com
Wed Jul 8 15:44:29 UTC 2026 

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.
