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. linux/module.h appears in roughly 15k #include directives across the kernel. This makes it a "hot" header, so it should avoid pulling in unnecessary definitions. 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 v3: - Rebase on top of v7.3-rc2. - Clean up commit descriptions. - Link to v2: https://patch.msgid.link/20260721131207.803760-1-petr.pavlu@suse.com 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://patch.msgid.link/20260708154510.6794-1-petr.pavlu@suse.com --- 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 arch/x86/kernel/cpu/mce/dev-mcelog.c | 2 +- drivers/block/drbd/drbd_nl.c | 1 + drivers/greybus/svc_watchdog.c | 1 + drivers/macintosh/windfarm_core.c | 1 + drivers/pnp/pnpbios/core.c | 2 +- drivers/video/fbdev/uvesafb.c | 1 + fs/coredump.c | 2 +- fs/nfs/cache_lib.c | 2 +- fs/nfsd/nfs4layouts.c | 2 +- fs/nfsd/nfs4recover.c | 1 + fs/ocfs2/stackglue.c | 1 + include/linux/kmod.h | 12 ++---------- kernel/cgroup/cgroup-v1.c | 2 +- kernel/module/kmod.c | 1 + kernel/power/process.c | 2 +- kernel/reboot.c | 2 +- kernel/time/jiffies.c | 1 + kernel/umh.c | 2 +- lib/kobject_uevent.c | 2 +- net/bridge/br_stp_if.c | 2 +- security/keys/request_key.c | 2 +- security/tomoyo/common.h | 2 +- 22 files changed, 23 insertions(+), 23 deletions(-) --- base-commit: df2908090cda368b01ff43709f51890076c56157 change-id: 20260816-module-include-kmod-14d1a0e19462
