Title:
Undefined func on include/linux/huge_mm.h
Status in linux package in Ubuntu:
Confirmed
Bug description:
Functions from mm/huge_memory.c is exported with include/linux/huge_mm.h
header but only when
context CONFIG_TRANSPARENT_HUGEPAGE is defined , when
CONFIG_TRANSPARENT_HUGEPAGE is not set
missing errors from compiler i expect this on include/linux/huge_mm.h bellow:
#ifdef CONFIG_TRANSPARENT_HUGEPAGE
extern int copy_huge_pmd(struct mm_struct *dst_mm, struct mm_struct *src_mm,
pmd_t *dst_pmd, pmd_t *src_pmd, unsigned long addr,
struct vm_area_struct *vma);
#else
static inline int copy_huge_pmd(struct mm_struct *dst_mm, struct mm_struct
*src_mm,
pmd_t *dst_pmd, pmd_t *src_pmd, unsigned long addr,
struct vm_area_struct *vma)
{
return 1;
}
#endif
Ensuring to exist defined function when CONFIG_TRANSPARENT_HUGEPAGE is not
set.
On this momment errors message from compiler is suppressed when
CONFIG_TRANSPARENT_HUGEPAGE is not set.
