block: merge struct block_device and struct hd_struct

2020-12-01T21:53:40+00:00

Instead of having two structures that represent each block device with
different life time rules, merge them into a single one.  This also
greatly simplifies the reference counting rules, as we can use the inode
reference count as the main reference count for the new struct
block_device, with the device model reference front ending it for device
model interaction.

Move the partition_meta_info to struct block_device in preparation for
killing struct hd_struct.

init: cleanup match_dev_by_uuid and match_dev_by_label

2020-12-01T21:53:39+00:00

Avoid a totally pointless goto label, and use the same style of
comparism for both helpers.

init: refactor devt_from_partuuid

2020-12-01T21:53:39+00:00

The code in devt_from_partuuid is very convoluted.  Refactor a bit by
sanitizing the goto and variable name usage.

init: refactor name_to_dev_t

2020-12-01T21:53:39+00:00

Split each case into a self-contained helper, and move the block
dependent code entirely under the pre-existing #ifdef CONFIG_BLOCK.
This allows to remove the blk_lookup_devt stub in genhd.h.

init: add an init_chroot helper

2020-07-31T06:17:52+00:00

Add a simple helper to chroot with a kernel space file name and switch
the early init code over to it.  Remove the now unused ksys_chroot.

init: add an init_mount helper

2020-07-31T06:17:51+00:00

Like do_mount, but takes a kernel pointer for the destination path.
Switch over the mounts in the init code and devtmpfs to it, which
just happen to work due to the implicit set_fs(KERNEL_DS) during early
init right now.

initrd: remove support for multiple floppies

2020-07-30T06:22:33+00:00

Remove the special handling for multiple floppies in the initrd code.
No one should be using floppies for booting these days. (famous last
words..)

Includes a spelling fix from Colin Ian King .
