Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

add_disk is now a "convenience" wrapper of device_add_disk. Unwrap it so
that callers can be later converted to handle error and attribute group
more easily.

Callers are converted with coccinelle:

@@
expression x;
@@
- add_disk(x)
+ device_add_disk(NULL, x)

Removal of add_disk and update of related comments are done manually.
