Subject: [patch 6/6][RFC] Drop CAP_SYS_RAWIO requirement on FIBMAP
Date: Fri, 26 Oct 2007 16:37:38 -0700 [thread overview]
Message-ID: <20071026233849.185498288@crlf.corp.google.com> (raw)
In-Reply-To: 20071026233732.568575496@crlf.corp.google.com
[-- Attachment #1: drop_cap_sys_rawio_for_fibmap.patch --]
[-- Type: text/plain, Size: 940 bytes --]
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.
