Linus,

can you please comment as of why batadv_mcast_mla_tt_retract() requires
to hold the tt.commit_lock ?


I see it calls batadv_tt_local_remove() but this does not really
requires the lock. Maybe you wanted to perform *all* the removes before
TT could do a commit ? Or is there any other reason?

Cheers,
