commit 28ab9769117ca944cb6eb537af5599aa436287a4 upstream.
SAT-5 revision 8 specification removed the text about the ANSI INCITS 431-2007 compliance which was requiring SCSI/ATA Translation (SAT) to return descriptor format sense data for the ATA PASS-THROUGH commands regardless of the setting of the D_SENSE bit.
Let's honor the D_SENSE bit for ATA PASS-THROUGH commands while generating the "ATA PASS-THROUGH INFORMATION AVAILABLE" sense data.
SAT-5 revision 7
12.2.2.8 Fixed format sense data
Table 212 shows the fields returned in the fixed format sense data (see SPC-5) for ATA PASS-THROUGH commands. SATLs compliant with ANSI INCITS 431-2007, SCSI/ATA Translation (SAT) return descriptor format sense data for the ATA PASS-THROUGH commands regardless of the setting of the D_SENSE bit.

Hello Greg,
This commit unfortunately breaks hdparm, hddtemp and udisks, and I have just sent a PR to Linus that reverts this commit, see: https://lore.kernel.org/linux-ide/20240815124310.1349324-1-cassel@kernel.org... and https://git.kernel.org/pub/scm/linux/kernel/git/libata/linux.git/commit/?h=a...
So it might be a good idea to not include this patch in v5.15.x in the first place, so that we avoid having a v5.15.x release that will be broken until the revert gets backported (in v5.15.x+1).
Kind regards, Niklas
