Hi,
Looking at init_mm initialization in 2.4 I am
wondering why is the INIT_MM like the way it is:
#define INIT_MM(name) \
{ \
mm_rb: RB_ROOT, \
pgd: swapper_pg_dir, \
mm_users: ATOMIC_INIT(2), \
mm_count: ATOMIC_INIT(1), \
mmap_sem: __RWSEM_INITIALIZER(name.mmap_sem), \
page_table_lock: SPIN_LOCK_UNLOCKED, \
mmlist: LIST_HEAD_INIT(name.mmlist), \
}
it is only called as
struct mm_struct init_mm = INIT_MM(init_mm);
so whats the reason of having name.mmap_sem and
name. mmlist in INIT_MM, is it to force some kind of
default initialization or so?
Thanks in advance.
