glusterfs.git/libglusterfs/src/circ-buff.c, branch v3.3.0qa32 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. libglusterfs: Implement circular buffer and event history 2012-02-20T14:59:11+00:00 Raghavendra Bhat raghavendrabhat@gluster.com 2012-02-20T13:12:37+00:00 db20a0f8a99f715a77366e518720612f043d5c9e Implement circular buffer framework, so that it can be used by other components such as event history management. And event history is implemented which can be used by xlator to dump some information to a file (such as information of some structure etc). Through statedump, history of each xlator can be dumped. An option called history should be given to the statedump command.
