I found that below services are not available with RHEL7. Please find details below. Can any one please confirm this
1.readahead_early
2.readahead_later
Both these services are for boot caching. Could not find these or related services in RHEL7
3. xfs
For RHEL 7 Supported XFS by default. Hence I guess no external service is provided. For more details check link below,
