Re: [PATCH net-next 1/2] ieee802154: sparse warnings: make symbols static

Dear Eric,

quoted

static DEFINE_SPINLOCK(flist_lock);

and of course commit 768f7c7c121e80f4 (6lowpan: add missing
spin_lock_init() ) must be reverted.

You should validate this code with LOCKDEP

lowpan_dellink() does a spin_lock(&flist_lock);
while same lock can be taken by lowpan_fragment_timer_expired() from
timer irq, -> deadlock.

del_timer() probably needs a del_timer_sync() too

Thanks a lot for the hints!

Alex
