Mike Christie f7d7129c6c scsi: sr: Fix sshdr use in sr_get_events
If scsi_execute_cmd returns < 0, it doesn't initialize the sshdr, so we
shouldn't access the sshdr. If it returns 0, then the cmd executed
successfully, so there is no need to check the sshdr. This has us access
the sshdr when we get a return value > 0.

 lpfc, qla2xxx).  We have a couple of major core changes impacting
 other systems: Command Duration Limits, which spills into block and
 ATA and block level Persistent Reservation Operations, which touches

Christoph Hellwig 05bdb99653 block: replace fmode_t with a block-specific type for block open flags
The only overlap between the block open flags mapped into the fmode_t and
other uses of fmode_t are FMODE_READ and FMODE_WRITE.  Define a new
blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and
->ioctl and stop abusing fmode_t.

Commit 2e27f576ab ("scsi: scsi_ioctl: Call scsi_cmd_ioctl() from
scsi_ioctl()") seems to have a typo as it is checking ret instead of cmd in
the if statement checking for CDROMCLOSETRAY and CDROMEJECT.  This changes
the behaviour of these ioctls as the cdrom_ioctl handling of these is more
restrictive than the scsi_ioctl version.

Lukas Bulwahn 79d45f57a1 sr: simplify the local variable initialization in sr_block_open()
Commit 01d0c69853 ("sr: implement ->free_disk to simplify refcounting")
refactored sr_block_open(), initialized one variable with a duplicate
assignment (probably an unintended copy & paste duplication) and turned one
error case into an early return, which makes the initialization of the
return variable needless.

So, simplify the local variable initialization in sr_block_open() to make
the code a bit more clear.

No functional change. No change in resulting object code.

Christoph Hellwig 1ebe2e5f9d block: remove GENHD_FL_EXT_DEVT
All modern drivers can support extra partitions using the extended
dev_t.  In fact except for the ioctl method drivers never even see
partitions in normal operation.

So remove the GENHD_FL_EXT_DEVT and allow extra partitions for all
block devices that do support partitions, and require those that
do not support partitions to explicit disallow them using
GENHD_FL_NO_PART.

Christoph Hellwig 1a827ce1b9 block: remove GENHD_FL_CD
GENHD_FL_CD marks a gendisk as a vaguely CD-ROM like device.
Besides being used internally inside of sunvdc.c an xen-blkfront it
is used by xen-blkback as a hint to claim a device exported to a
guest is a CD-ROM like device.  Just check for disk->cdi instead
which is the right indicator for "real" CD-ROM or DVD drivers.  This
will miss the paravirtualized guest drivers, but those make little
sense to report anyway.

Li Manyi 5c04243a56 scsi: sr: Return correct event when media event code is 3
Media event code 3 is defined in the MMC-6 spec as follows:

  "MediaRemoval: The media has been removed from the specified slot, and
   the Drive is unable to access the media without user intervention. This
   applies to media changers only."

This indicated that treating the condition as an EJECT_REQUEST was
appropriate. However, doing so had the unfortunate side-effect of causing
the drive tray to be physically ejected on resume. Instead treat the event
as a MEDIA_CHANGE request.
