It's an optional device feature, so this should be OK
(although the iSER driver currently seems to depend on a device
supporting FMRs, which is probably going to be a problem with iWARP
support in the future anyway).

I don't feel very well with removing code from the driver that iSER seems to depend on. Are there plans to fix this in iSER?

What is the fix you suggest, to add a device query that tells you for which verbs the documentation does not apply? or enhance the code of the map_phys_fmr verb within the ehca driver to return error if called from non-sleepable context?

Or.
