Subject:    [patch 6/6][RFC] Drop CAP_SYS_RAWIO requirement on FIBMAP

[Download RAW message or body]

Remove the need for having CAP_SYS_RAWIO when doing a FIBMAP call on an open file \
descriptor.

It would be nice to allow users to have permission to see where their data is landing \
on disk, and there really isn't a good reason to keep them from getting at this \
information.
