Dear Linus, Dear Martin,
About fifteen years ago, soon after I got interested in SMART and
starting working on smartmontools, I wrote some kernel code that added
smart data into /sys. (Actually this was around the 2.4 transition so it
was under /proc along with lots of other stuff that had nothin

also worth noting that HDD temperature sensors are notoriously

I am sorry if you think that D-Link does bad engineering, what I
am trying to achieve is upstream support for this device, without
any out-of-tre

The problem with all this is that the storage topology is largely
undiscoverable for monitoring purposes. We can use heuristics, but in
many cases there is no r
S.M.A.R.T. temperature sensors have been supported for
years by userspace tools such as smarttools and hddtemp.
This adds support to read it from the kernel using
the hwmon API and adds a temperature zone for the drive.
The idea came about when experimenting with NAS enclosures
