Hi Eric,
After merging the userns tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:
In file included from include/linux/sched.h:16:0,
from arch/powerpc/lib/xor_vmx_glue.c:14:
include/linux/shm.h:17:35: error: 'struct file' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
bool is_file_shm_hugepages(struct file *file);
^~~~
and many, many more (most warnings, but some errors - arch/powerpc is
mostly built with -Werror)
Maybe caused by commit
1a5c1349d105 ("sem: Move struct sem and struct sem_array into ipc/sem.c")
I have appplied the following fix patch for today:
