New Revision: 309297
URL: https://svnweb.freebsd.org/changeset/base/309297
Log:
Make SES status updates more aggressive.
- On control request update all status pages, since they may also be
affected if user enables/disables enclosure slots.
- Periodically update element descriptors too, since there is some
hardware where they are changed dynamically.
