To provide another small data point:
Tested-by: Thorsten Leemhuis <linux at leemhuis.info>
A "Compile-Tested-by", to be precise: after a handful similar patches
reached mainline recently this is the only one I still need to compile
the pretty broad Fedora rawhide config on rawhide using the GCC 15
pre-release it currently includes. The latter or the final will
hopefully soon also reach Fedora 42 beta as well and bring the "[1]"
mentioned in the patch description above to F42 -- which will be
released in a few weeks, so I guess it would be nice to have this patch
mainlined rather sooner that later to avoid more people running into this.
HTH, ciao, Thorsten
