Hi Shuah, Edward and all,

This patch now seems to be obsolete, due to Edward Liaw's comprehensive
fix, "[PATCH v2 0/5] Define _GNU_SOURCE for sources using" [1].

[1] https://lore.kernel.org/20240507214254.2787305-1-edliaw@xxxxxxxxxx

Since we're dropping that patch, would we be able to merge this one?
This should resolve the futex_requeue_pi compiler warnings with Clang.

Thanks for the review! I can post a v2 of this tiny series that has only
patches 1 and 3, rebased on -rc1, so that it's clear what to merge.


thanks,
