Christian Brauner 3b5bbe798b pidfd: prevent creation of pidfds for kthreads ... It's currently possible to create pidfds for kthreads but it is unclear what that is supposed to mean. Until we have use-cases for it and we figured out what behavior we want block the creation of pidfds for kthreads. Link: https://lore.kernel.org/r/20240731-gleis-mehreinnahmen-6bbadd128383@brauner Fixes: 32fcb426ec ("pid: add pidfd_open()") Cc: stable@vger.kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org>		2024-08-12 22:03:26 +02:00
