This is a note to let you know that I've just added the patch titled
md: call del_gendisk in control pathto the 6.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...
The filename of the patch is: md-call-del_gendisk-in-control-path.patch and it can be found in the queue-6.6 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.
This patch should be be backported to any stable kernel, this change will break user tools mdadm:
https://lore.kernel.org/all/f654db67-a5a5-114b-09b8-00db303daab7@redhat.com/
Is it reverted in Linus's tree?
No, we'll not revert it, this is an improvement. In order to keep user tools compatibility, we added a switch in the kernel. As discussed in the thread, for old tools + new kernel, functionality is the same, however, there will be kernel warning about deprecated behaviour to inform user upgrading user tools.
However, I feel this new warning messages is not acceptable for stable kernels.
Thanks, Kuai
