Upstream: no If user want to reuse one ASID for many CSV guests, he should provide a label (i.e. userid) and the length of the label when launch CSV guest. The reference count of the ASID will be increased if user launch a CSV guest with the label correspond to the ASID. When a CSV guest which launch with a label is destroyed, the reference count of the ASID correspond to the label will be decreased, and the ASID is freed only if the reference count becomes zero. The codes for reuse ASID is not compatible with CONFIG_CGROUP_MISC, we introduce CONFIG_KVM_SUPPORTS_CSV_REUSE_ASID that depends on !CGROUP_MISC, the code take effect only when CONFIG_KVM_SUPPORTS_CSV_REUSE_ASID=y.

README
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.
