scsi: libsas: Introduce more SAM status code aliases in enum exec_status

2021-06-02T20:10:46Z

This patch prepares for converting SAM status codes into an enum. Without this patch converting SAM status codes into an enumeration type would trigger complaints about enum type mismatches for the SAS code.

scsi: libsas: Tidy SAS address print format

2019-12-21T18:42:42Z

Currently we use a mixture of %016llx, %llx, and %16llx when printing a SAS address. Since the most significant nibble of the SAS address is always 5 - as per standard - this formatting is not so important; but some fake SAS addresses for SATA devices may not be. And we have mangled/invalid address to consider also. And it's better to be consistent in the code, so use a fixed format. The SAS address is a fixed size at 64b, so we want to 0 byte extend to 16 nibbles, so use %016llx globally. Also make some prints to be explicitly hex, and tidy some whitespace issue.

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45Z

Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

scsi: libsas: Drop SAS_DPRINTK() and revise logs levels

2018-11-15T19:37:06Z

Like sas_printk() did previously, SAS_DPRINTK() offers little value now that libsas logs already have the "sas" prefix through pr_fmt(fmt). So it can be dropped. However, after reviewing some logs in libsas, it is noticed that debug level is too low in many instances. So this change drops SAS_DPRINTK() and revises some logs to a more appropriate level. However many stay at debug level, although some are significantly promoted. We add -DDEBUG for compilation so that we keep the debug messages by default, as before. All the pre-existing checkpatch errors for spanning messages across multiple lines are also fixed. Finally, all other references to printk() [apart from special formatting in sas_ata.c] are removed and replaced with appropriate pr_xxx().

scsi: libsas: Use pr_fmt(fmt)

2018-11-15T19:37:05Z

In preparation for dropping the libsas printk wrappers, use pr_fmt(fmt) declaration to add the framework log prefix - "sas". Suggested-by: Joe Perches Signed-off-by: John Garry Signed-off-by: Martin K. Petersen

scsi: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

2011-10-31T23:31:23Z

For the basic SCSI infrastructure files that are exporting symbols but not modules themselves, add in the basic export.h header file to allow the exports. Signed-off-by: Paul Gortmaker

[SCSI] Unify SAM_ and SAM_STAT_ macros

2010-07-28T14:07:49Z

We have two separate definitions for identical constants with nearly the same name. One comes from the generic headers in scsi.h; the other is an enum in libsas.h ... it's causing confusion about which one is correct (fortunately they both are). Fix this by eliminating the libsas.h duplicate Signed-off-by: James Bottomley

[SCSI] libsas: abstract STP task status into a function
