Not anything particular. Lets see: $ git --no-pager grep "mutex_lock(&module_mutex)" arch/powerpc/platforms/powernv/pci-cxl.c: mutex_lock(&module_mutex); drivers/gpu/drm/drm_fb_helper.c: mutex_lock(&module_mutex); include/linux/module.h: mutex_lock(&module_mutex); kernel/livepatch/core.c: mutex_lock(&module_mutex); kernel/livepatch/core.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); kernel/module.c: mutex_lock(&module_mutex); I could refine this commit to patch these sites. Or should I split it into multiple? /Jarkko
