blk-mq: remove ->map_queue

2016-09-15T14:42:03+00:00

All drivers use the default, so provide an inline version of it.  If we
ever need other queue mapping we can add an optional method back,
although supporting will also require major changes to the queue setup
code.

This provides better code generation, and better debugability as well.

mtip32xx: mark symbols static where possible

2016-08-29T14:13:21+00:00

We get 1 warning when biuld kernel with W=1:
drivers/block/mtip32xx/mtip32xx.c:3689:6: warning: no previous prototype for
 'mtip_block_release' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is declared
and don't need a declaration, but can be made static.
so this patch marks it 'static'.

block: convert to device_add_disk()

2016-06-27T19:26:08+00:00

For block drivers that specify a parent device, convert them to use
device_add_disk().

This conversion was done with the following semantic patch:

    @@
    struct gendisk *disk;
    expression E;
    @@

    - disk->driverfs_dev = E;
    ...
    - add_disk(disk);
    + device_add_disk(E, disk);

    @@
    struct gendisk *disk;
    expression E1, E2;
    @@

    - disk->driverfs_dev = E1;
    ...
    E2 = disk;
    ...
    - add_disk(E2);
    + device_add_disk(E1, E2);

...plus some manual fixups for a few missed conversions.

drivers: use req op accessor

2016-06-07T19:41:38+00:00

The req operation REQ_OP is separated from the rq_flag_bits
definition. This converts the block layer drivers to
use req_op to get the op from the request struct.

mtip32xx: remove call to blk_queue_flush()

2016-04-12T22:00:39+00:00

The driver calls it with 0 for flags, since it doesn't have a writeback
cache. Just remove the call, as it's a no-op right now.

mtip32xx: remove unneeded variable in mtip_cmd_timeout()

2016-03-04T15:15:48+00:00

We always return BLK_EH_RESET_TIMER, so no point in storing that in
an integer.
