Hi, thank you for your reply.
I hope this is enough information for you to debug the issue.
I am standing by for any additional diagnostics needed.
Won't userfaultfd.c fail in a similar way?
Anyhow, khugepaged.c jas
#ifndef MADV_PAGEOUT
#define MADV_PAGEOUT 21
#endif
So most probably we should do the same.
Actually, David, it turned out that userfaultfd.c compiled
out-of-the-box, and side-by-side comparison showed that it also included
"/home/marvin/linux/kernel/linux_torvalds/usr/include/asm-generic/mman-common.h"
The only remaining difference was including <linux/mman.h>, which fixed
the issue w/o #ifdef ... #endif
Hope this helps.
Please find the following diff.
