From ec4b62705df85a5df06806c4b8b5a04c7e4a5846 Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Thu, 26 Sep 2019 17:46:27 +0200 Subject: msgb: Allow size==headroom in msgb_alloc_headroom*() Nothinh really forbids this case, it's totally fine allocating all space of msgb as headroom. osmo-pcu actually does that in gprs_rlcmac_ul_tbf::snd_ul_ud().
