From dc6be97bccd86cfbd64586a5fd9faefb673b70a6 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Thu, 20 Jun 2019 22:00:34 +0200 Subject: lib: Add tests for the shm_rbuff This adds some tests for the shm_rbuff after some reports that the queue length would be erroneously reported as 0 when the rbuff was full. The test passes for the reported case.
