/home/rpjday/k/git/usr/include/linux/kexec.h:49: userspace cannot
reference function or variable defined in the kernel
...
sure enough, here's that part of the exported kexec.h header file:
#ifndef __KERNEL__
/*
* This structure is used to hold the arguments that are used when
* loading kernel binaries.
*/
struct kexec_segment {
const void *buf;
size_t bufsz;
const void *mem;
size_t memsz;
};
/* Load a new kernel image as described by the kexec_segment array
* consisting of passed number of segments at the entry-point address.
* The flags allow different useage types.
*/
extern int kexec_load(void *, size_t, struct kexec_segment *,
unsigned long int);
#endif /* __KERNEL__ */
seems pretty clear that there's no point exporting the declaration
of kexec_load() to user space, correct?
