there are several reasons for this:
1) evs is only partially implemented with no plans to complete it
typedef enum {
EVS_TYPE_UNORDERED, /* not implemented */
EVS_TYPE_FIFO, /* same as agreed */
EVS_TYPE_AGREED,
EVS_TYPE_SAFE /* not implemented */
} evs_guarantee_t;
2) evs has no users in any upstream distribution and no search
engine can find any other upstream using it.
3) the only reason (I was told) to carry around evs was that evs
receives the full ring_id struct from totem. This is only
partially correct because while the structures are prepared
to carry around those data, they are never transmitted from
corosync engine down the IPC line to the user.
CPG ring_id contains the exact same information and it's
actually less buggy (due to prototying of the info).
worst case scenario where a user really absolutely need libevs,
it can be easily reimplemented as libcpg wrapper and avoid
lots of code duplication.

Some switches delay multicast packets vs the unicast token. This patch works
around that problem by providing a new tuneable called miss_count_const. This
tuneable works by counting the number of times a message is found missing
and once reaching the const value, marks it as missing in the retransmit list.
This improves performance and doesn't display warning messages about missed
multicast messages when operating in these switching environments.

The UDPU transport is useful for those deployments which can't use multicast.
UDPU works by using UDP unicast, which is fully supported by every switch

An example of the UDPU transport is contained in the corosync.conf.example.udpu
file which shows a 16 node cluster. This file should be copied to each node
in the cluster and IP addresses changed as appropriate.

The flight recoder buffer size as specified in LOGSYS_DECLARE_SYSTEM
or _logsys_rec_init was expressed in number of ints. A developer asking
to allocate 512K would get a 2M allocation on a machine with sizeof(int) = 4.
This is confusing and the patch addresses it:
- rename rec_size to fltsize for external API (no type change),
because rec_size is used many times internally for other reasons
and it can be confusing.
- rename size to fltsize in _logsys_rec_init.
- document what we allocate and why.
- swap comments around to match the code.
- introduce a simple macro to perform rounding (stolen from linux-2.6.git).
- start shaping fdata header to better handle dynamic values:
* write the flt_data_size as first unsigned int the header.
* change corosync-fplay to read the value and alloc the right amount
of memory instead of hardcoding it again.
