block: add a bdget_part helper

2020-10-05T16:38:33+00:00

All remaining callers of bdget() outside of fs/block_dev.c want to get a
reference to the struct block_device for a given struct hd_struct.  Add
a helper just for that and then mark bdget static.

block: use bd_partno in bdevname

2020-09-25T14:18:58+00:00

No need to go through the hd_struct to find the partition number.

block: cleanup partition scanning in register_disk

2020-09-23T16:43:19+00:00

Use blkdev_get_by_dev instead of open coding it using bdget_disk +
blkdev_get, and split the code to read the partition table into a
separate helper to make it a little more obvious.

block: move the NEED_PART_SCAN flag to struct gendisk

2020-09-23T16:43:18+00:00

We can only scan for partitions on the whole disk, so move the flag
from struct block_device to struct gendisk.

block: add a bdev_check_media_change helper

2020-09-10T15:32:30+00:00

Like check_disk_changed, except that it does not call ->revalidate_disk
but leaves that to the caller.

block: use revalidate_disk_size in set_capacity_revalidate_and_notify

2020-09-02T14:00:07+00:00

Only virtio_blk and xen-blkfront set the revalidate argument to true,
and both do not implement the ->revalidate_disk method.  So switch
to the helper that just updates the size instead.

block: rename bd_invalidated

2020-09-02T14:00:02+00:00

Replace bd_invalidate with a new BDEV_NEED_PART_SCAN flag in a bd_flags
variable to better describe the condition.

We can trivially derive the gendisk from the hd_struct.
