VirtIO 1.0 spec says:
The removed and rescan events ... when sent for LUN 0, they MAY
apply to the entire target so the driver can ask the initiator
to rescan the target to detect this.
This change introduces the behaviour described above by scanning the entire
SCSI target when LUN is set to 0. This is both a functional and a
performance fix. It aligns the driver with the spec and allows control
planes to hotplug targets with large numbers of LUNs without having to
request a RESCAN for each one of them.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
