glusterd: Use uint32_t for peerinfo generation number
Using a uint64_t for the peerinfo generation number was overkill for how the generation number is used within GlusterD. It also prevented GlusterD from running on 32-bit architechtures, as uatomic_add_return doesn't support 64-bit values on 32-bit architechtures. This change was developed on the git branch at [1]. This commit is a combination of the following commits on the development branch. b78dba4 Use 32-bit generation number 2c37e4b Change other generation number variables to uint32_t [1]: https://github.com/kshlm/glusterfs/tree/urcu Change-Id: I0f310f56a4fb97d6bcbc23255a379ed5bb1ed9e1 BUG: 1205186 Signed-off-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.org/10425 Reviewed-by: Anand Nekkunti <anekkunt@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Emmanuel Dreyfus <manu@netbsd.org> Tested-by: Emmanuel Dreyfus <manu@netbsd.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Krishnan Parthasarathi <kparthas@redhat.com>
