Even after commit908d4bb7c5("qede: fix interrupt coalescing configuration"), some entries of the coal_entry array may theoretically be used uninitialized: 1. qede_alloc_fp_array() allocates QEDE_MAX_RSS_CNT entries for coal_entry. The initial allocation uses kcalloc, so everything is initialized. 2. The user sets a small number of queues (ethtool -L). coal_entry is reallocated for the actual small number of queues. 3. The user sets a bigger number of queues. coal_entry is reallocated bigger. The added entries are not necessarily initialized. In practice, the reallocations will actually keep using the originally allocated region of memory, but we should not rely on it. The reallocation is unnecessary. coal_entry can always have QEDE_MAX_RSS_CNT entries.

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.
