From 744886ae96d74cb60ef03bb209d46b250af54612 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Thu, 23 May 2019 21:58:21 +0200 Subject: chan_alloc: Don't include CBCH channels in load computation When displaying the channel (lchan) load, we are interested in the dedicated channels as available for communication with mobile stations. If CBCH is enabled, it "steals" one of the SDCCH slots, so we have to exclude this channel from the count of available dedicated channels. Before this patch, A CBCH would show up as "in use" dedicated channel (so both the total and the in_use count were incremented). After this patch, neither "total" nor "use" are affected; The CBCH slot is completely excluded from load statistics.
