Linux kernel source tree

In case of an error, ublk's ->uring_cmd() functions currently return -EIOCBQUEUED and immediately call io_uring_cmd_done(). -EIOCBQUEUED and io_uring_cmd_done() are intended for asynchronous completions. For synchronous completions, the ->uring_cmd() function can just return the negative return code directly. This skips io_uring_cmd_del_cancelable(), and deferring the completion to task work. So return the error code directly from __ublk_ch_uring_cmd() and ublk_ctrl_uring_cmd(). Update ublk_ch_uring_cmd_cb(), which currently ignores the return value from __ublk_ch_uring_cmd(), to call io_uring_cmd_done() for synchronous completions.

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.
