ktime: Cleanup ktime_set() usage

2016-12-25T16:21:22+00:00

ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment. Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra

scsi: scsi_debug: Fix memory leak if LBP enabled and module is unloaded

2016-10-27T02:14:50+00:00

map_storep was not being vfree()'d in the module_exit call. Cc: Signed-off-by: Ewan D. Milne Reviewed-by: Laurence Oberman Signed-off-by: Martin K. Petersen

scsi: sd: Move DIF protection types to t10-pi.h

2016-09-15T13:51:14+00:00

These should go together with the rest of the T10 protection information defintions. [mkp: s/T10_DIF/T10_PI/] Signed-off-by: Christoph Hellwig Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi: scsi_debug: Use struct t10_pi_tuple instead of struct sd_dif_tuple

2016-09-15T13:41:09+00:00

And remove the declaration of the latter in sd.h as scsi_debug was the only user. Signed-off-by: Christoph Hellwig Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi_debug: fix sleep in invalid context

2016-07-13T03:16:31+00:00

In this post: http://www.spinics.net/lists/linux-scsi/msg97124.html the author shows some kernel infrastructure complaining about a sleep in an invalid context. Remove offending call to vmalloc(). Instead of using kzalloc() which reviewers didn't like, use a bucket system (64 bytes on the stack) and potentially multiple calls to sg_pcopy_from_buffer() to construct the 'data-in' buffer for the SCSI REPORT LUNS command.

scsi_debug: use locally assigned naa

For reported SAS addresses replace fake IEEE registered NAAs (5) with locally assigned NAAs (3). Signed-off-by: Douglas Gilbert Reviewed-by: Hannes Reinecke Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi_debug: uuid for lu name

2016-05-11T01:25:34+00:00

Permit changing of a LU name from a (fake) IEEE registered NAA (5) to a locally assigned UUID. Using a UUID (RFC 4122) for a SCSI designation descriptor (e.g. a LU name) was added in spc5r08.pdf (a draft INCITS standard) on 25 January 2016. Add parameter uuid_ctl to use a separate UUID for each LU (storage device) name. Additional option for all LU names to have the same UUID (since their storage is shared). Previous action of using NAA identifier for LU name remains the default. Signed-off-by: Douglas Gilbert Reviewed-by: Hannes Reinecke Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi_debug: vpd and mode page work

2016-05-11T01:24:00+00:00

Cleanup some mode and vpd pages. Stop reporting SBC (disk) pages when peripheral type is something else (e.g. tape). Update version descriptors. Expand LBPRZ flag handling. Signed-off-by: Douglas Gilbert Reviewed-by: Hannes Reinecke Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi_debug: add multiple queue support

2016-05-11T01:22:38+00:00

Add submit_queue parameter (minimum and default: 1; maximum: nr_cpu_ids) that controls how many queues are built, each with their own lock and in_use bit vector. Add statistics parameter which is default off. Signed-off-by: Douglas Gilbert Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen
