which contain a realtime subvolume. The realtime subvolume is a
separate area of disk space where only file data is stored. It was
originally designed to provide deterministic data rates suitable
for media streaming applications, but is also useful as a generic
mechanism for ensuring data and metadata/log I/Os are completely
separated. Regular file I/Os are isolated to a separate device
from all other requests, and this can be done quite transparently
to applications via the inherit-realtime directory inode flag.
