[LTP] [PATCH v2 1/1] ioctl_pidfd06: Update kernel version

[LTP] [PATCH v2 1/1] ioctl_pidfd06: Update kernel version

[Petr Vorel]

Kernel commit ab89060fbc92e ("pidfs: return -EREMOTE when PIDFD_GET_INFO
is called on another ns") from v7.0 was backported into stable/LTS
kernels v6.18.14 (7446125afb6d9) and v6.19.10 (2920abaf56c09).
Update errnos for these stable/LTS kernels (do not treat older behavior
as an error).

Follow-up: f630471a6520 ("ioctl_pidfd06: Select expected errno for PIDFD_GET_INFO across pidns")
Reported-by: Wei Gao <wegao@suse.com>
Signed-off-by: Petr Vorel <pvorel@suse.cz>

Alternative approach for Wei's fix:
https://patchwork.ozlabs.org/project/ltp/patch/20260406023538.14739-1-wegao@suse.com/
https://lore.kernel.org/ltp/20260406023538.14739-1-wegao@suse.com/

Changes v1->v2:
* Cover also 6.19.0..v6.19.9
* Add Follow-up: tag (not Fixme: tag), commit was correct at the time.
