Subject: [PATCHv2 0/5] scsi: More detailed I/O errors
Date: Mon, 1 Jul 2013 10:12:06 +0200 [thread overview]
Message-ID: <1372666331-66996-1-git-send-email-hare@suse.de> (raw)
As discussed at LSF the SCSI stack already knows about several
error conditions, it's just not well documented.
Also there are some more conditions upper layers might be
interested in.
This patchset improves the documentation of the existing
I/O error codes and adds three more error codes, ENOSPC
for thin provisioning failure, ENODATA for medium error,
and ENXIO for an invalid or removed device.
Changes since the initial version:
- Correctly document all return codes in
__scsi_error_from_host_byte()
- Set hostbyte status in scsi_check_sense()
- Return ENXIO on invalid or removed device
Hannes Reinecke (5):
scsi: Document enhanced error codes
scsi: Set hostbyte status in scsi_check_sense()
scsi: return ENOSPC on thin provisioning failure
scsi: Return ENODATA on medium error
scsi: Return ENXIO on invalid device
