Re: include/linux/kprobes.h:332:2: error: invalid use of undefined type 'struct kprobe_ctlblk'
CC David Howells. It looks this error is specific to mn10300 and
allmodconfig/allyesconfig.
The last solution is to quiet reports for such old errors, if
mn10300-allmodconfig/allyesconfig are not interested combinations.
Thanks,
