diff --git a/mm/debug.c b/mm/debug.c index 9d3d893dc7f4..96d594e16292 100644 --- a/mm/debug.c +++ b/mm/debug.c @@ -215,6 +215,7 @@ void dump_mm(const struct mm_struct *mm) mm->def_flags, &mm->def_flags ); } +EXPORT_SYMBOL(dump_mm); static bool page_init_poisoning __read_mostly = true;
mmap_assert_write_locked() is used in vm_flags modifiers. Because mmap_assert_write_locked() uses dump_mm() and vm_flags are sometimes modified from from inside a module, it's necessary to export dump_mm() function.
