---------------------+--------------------
Tuned sets readahead for all devices to the same value. But a system
might have different storage devices attached that require different
readahead values (i.e. local storage vs flash).
Tuned should provide a way for users to specify readaheads on a per-device
basis. This could be implemented as a regex in the profile tuned.conf.
i.e.
readahead={4096,devices=*}
readahead={8192,devices=fio*}
Other example tunings that need this feature:
- I/O scheduler
- Filesystem barriers
