Linux kernel source tree
ffe0398c7d
For a command that is normally processed through the command request
execute() function, the completion entry for the command is initialized
by __nvmet_req_complete() and nvmet_pci_epf_cq_work() only needs to set
the status field and the phase of the completion entry before posting
the entry to the completion queue.
However, for commands that are failed due to an internal error (e.g. the
command data buffer allocation fails), the command request execute()
function is not called and __nvmet_req_complete() is never executed for
the command, leaving the command completion entry uninitialized. For
such command failed before calling req->execute(), the host ends up
seeing completion entries with an invalid submission queue ID and
command ID.
Avoid such issue by always fully initilizing a command completion entry
in nvmet_pci_epf_cq_work(), setting the entry submission queue head, ID
and command ID.

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 reStructuredText 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.
