# ENTERPRISE VERSION RED HAT STORAGE (from 1.3)
# This version is only supported on RHEL 7.1
# As of RHEL 7.1, libceph.ko and rbd.ko are now included in Red Hat's kernel
# packages natively. The RHEL 7.1 kernel packages are more stable and secure than
# using these 3rd-party kmods with RHEL 7.0. Please update your systems to RHEL
# 7.1 or later if you want to use the kernel RBD client.
#
# The CephFS kernel client is undergoing rapid development upstream, and we do
# not recommend running the CephFS kernel module on RHEL 7's 3.10 kernel at this
# time. Please use ELRepo's latest upstream 4.x kernels if you want to run CephFS
# on RHEL 7.
