Hi Phillip, It turns out that this patch was based on an old github repository that doesn't appear to be updated. Doug Gilbert reached out after the initial RFC and directed us to his page (http://sg.danny.cz/sg/) where he has updated sg3_utils code. As we continue to work through the feedback from our SSHD kernel patches, I'm going to follow up with Doug again on sg3_utils. > -----Original Message----- > From: Phillip Susi [mailto:psusi@xxxxxxxxxx] > Sent: Monday, November 24, 2014 4:34 PM > To: Akers, Jason B; linux-ide@xxxxxxxxxxxxxxx > Cc: Karkra, Kapil; Williams, Dan J; linux-kernel@xxxxxxxxxxxxxxx; > dgilbert@xxxxxxxxxxxx > Subject: Re: [RFC PATCH] sg3_utils: Added hybrid information log utility > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA512 > > On 10/29/2014 03:57 PM, Jason B.
