That's strange, I got an email shortly after the patch got into mailinine about the backport: Subject: Patch "loop: Disable fallocate() zero and discard if not supported" has been added to the 6.9-stable tree Reply-To: stable@vger.kernel.org This is a note to let you know that I've just added the patch titled loop: Disable fallocate() zero and discard if not supported to the 6.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: loop-disable-fallocate-zero-and-discard-if-not-suppo.patch and it can be found in the queue-6.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let know about it. commit 6718aa792b7d297ece53024a138ea679e8153ea6 Author: Cyril Hrubis Date: Thu Jun 13 18:38:17 2024 +0200 loop: Disable fallocate() zero and discard if not supported -- Cyril Hrubis chrubis@suse.cz
