Branch: refs/heads/master Home: https://github.com/fabbione/kronosnet Commit: b0c959ae7d2083c822e396ea72d41811962f821c https://github.com/fabbione/kronosnet/commit/b0c959ae7d2083c822e396ea72d418… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2017-06-24 (Sat, 24 Jun 2017) Changed paths: M libknet/link.c Log Message: ----------- [link] switch link_get_status to write lock previous to the introduction of detailed link stats, the values contained in the status structure would hardly change over time making a rdlock more than enough to get the right data. Now that the values are updated constantly, we need to remove the window of thread X writing values and thread Y to read them while being written. Signed-off-by: Fabio M.
