Greg Kroah-Hartman 59ecec707d Revert "net/mlx5: Annotate mutex destroy for root ns" 
This reverts commit 95fde2e468 which is
commit 9ca415399dae133b00273a4283ef31d003a6818d upstream.

It was backported incorrectly, Paul writes at:
	https://lore.kernel.org/r/20200607203425.GD23662@windriver.com

	I happened to notice this commit:

	9ca415399dae - "net/mlx5: Annotate mutex destroy for root ns"

	...was backported to 4.19 and 5.4 and v5.6 in linux-stable.

	It patches del_sw_root_ns() - which only exists after v5.7-rc7 from:

	6eb7a268a99b - "net/mlx5: Don't maintain a case of del_sw_func being
	null"

	which creates the one line del_sw_root_ns stub function around
	kfree(node) by breaking it out of tree_put_node().

	In the absense of del_sw_root_ns - the backport finds an identical one
	line kfree stub fcn - named del_sw_prio from this earlier commit:

	139ed6c6c4 - "net/mlx5: Fix steering memory leak"  [in v4.15-rc5]

	and then puts the mutex_destroy() into that (wrong) function, instead of
	putting it into tree_put_node where the root ns case used to be hand

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
