That patch never touched "./usr/include/scsi/sg.h" but the error line
does correspond with include/uapi/scsi/sg.h . That file does include
<linux/types.h> on line 31 which should take care of defining size_t
within the kernel.
But is this a user space compilation check? According to cppreference.com
for C size_t is defined in:
Defined in header <stddef.h>
Defined in header <stdio.h>
Defined in header <stdlib.h>
Defined in header <string.h>
Defined in header <time.h>
Defined in header <uchar.h> (since C11)
Defined in header <wchar.h> (since C95)
So is a solution to include <stddef.h> ? Or should <linux/types.h> do
that if it only conditionally defines size_t ? Or am I on the wrong
track?
