pespin gerrit-no-reply at lists.osmocom.orgpespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-pcu/+/22295 )
Change subject: Convert gprs_bssgp_pcu.cpp to C
......................................................................
Convert gprs_bssgp_pcu.cpp to C
There's no real use of C++ in that file, and it causes problems when
using llist_head entry macros in future patches adding initial support
for multiple BTS in PCU object, so let's move it to plain C.
