No functional change. Just introduce scsi_host_busy() and replace the direct read of scsi_host->host_busy with this new API. Cc: Omar Sandoval , Cc: "Martin K.

scsi: core: check for equality of result byte values

2018-06-26T16:27:06+00:00

When evaluating a SCSI command's result using the field access macros, check for equality of the fields and not if a specific bit is set. This is a preparation patch, for reworking the results field in the SCSI command.

scsi: Rework handling of scsi_device.vpd_pg8[03]

2017-08-30T01:51:42+00:00

Introduce struct scsi_vpd for the VPD page length, data and the RCU head that will be used to free the VPD data. Use kfree_rcu() instead of kfree() to free VPD data. Move the VPD buffer pointer check inside the RCU read lock in the sysfs code. Only annotate pointers that are shared across threads with __rcu. Use rcu_dereference() when dereferencing an RCU pointer. This patch suppresses about twenty sparse complaints about the vpd_pg8[03] pointers. This patch also fixes a race condition, namely that updating of the VPD pointers and length variables in struct scsi_device was not atomic with reference to the code reading these variables. See also "Does the update code tolerate concurrent accesses?" in Documentation/RCU/checklist.txt.

Introduce the scsi_get_vpd_buf() and scsi_update_vpd_page() functions. The only functional change in this patch is that if updating page 0x80 fails that it is attempted to update page 0x83.

Revert "scsi: default to scsi-mq"

2017-08-17T00:01:32+00:00

Defaulting to scsi-mq in 4.13-rc has shown various regressions on setups that we didn't previously consider. Fixes for them are in progress, but too invasive to make it in this cycle. So for now revert the commit that defaults to blk-mq for SCSI. For 4.14 we'll plan to try again with these fixes. This reverts commit 5c279bd9e40624f4ab6e688671026d6005b066fa.
