From b0708d3e769851093ef633844d894b683a3c0341 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Mon, 4 Feb 2019 12:09:05 +0100 Subject: bitvec: Add bitvec_tailroom_bits() function This is similar to msgb_tailroom(): It returns the amount of space left at the end of the bit vector (compared to the current cursor). The function returns the number of bits left in the bitvec.
