Evict alloc/free stack traces from the stack depot for Generic KASAN once they are evicted from the quaratine. For auxiliary stack traces, evict the oldest stack trace once a new one is saved (KASAN only keeps references to the last two). Also evict all saved stack traces on krealloc. To avoid double-evicting and mis-evicting stack traces (in case KASAN's metadata was corrupted), reset KASAN's per-object metadata that stores stack depot handles when the object is initialized and when it's evicted from the quarantine. Note that stack_depot_put is no-op if the handle is 0.

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.
