Some functions already have documentation about locks they require inside
their kerneldoc header. These can be directly tested during runtime using
the lockdep asserts.

Functions which use (h)list_del* are requiring correct locking when they
operate on global lists. Most of the time the search in the list and the
delete are done in the same function. All other cases should have it
visible that they require a special lock to avoid race conditions.

Lockdep asserts can be used to check these problem during runtime when the
lockdep functionality is enabled.

The TVLV for the gw_bandwidth stores everything as u32. But the
gw_bandwidth reads the signed long which limits the maximum value to
(2 ** 31 - 1) on systems with 4 byte long. Also the input value is always
converted from either Mibit/s or Kibit/s to 100Kibit/s. This reduces the
values even further when the user sets it via the default unit Kibit/s. It
may even cause an integer overflow and end up with a value the user never
intended.

Instead read the values as u64, check for possible overflows, do the unit
adjustments and then reduce the size to u32.

The hlist_del_rcu() call in batadv_tt_global_size_mod() does not check
if the element still is part of the list prior to deletion. The atomic
list counter should prevent the worst but converting to
hlist_del_init_rcu() ensures the element can't be deleted more than
once.

 - Adds support in ILA to precompute checksum difference for
