The PCIe devices supported by the PTT trace can be removed/rescanned by hotplug or through sysfs. Add support for dynamically updating the available filter list by registering a PCI bus notifier block. Then user can always get latest information about available tracing filters and driver can block the invalid filters of which related devices no longer exist in the system.

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.
