From: "Saad Varshani" To: , X-Mailer: aerc 0.22.0 Hello, I was investigating bug report ad6c1104e51702ef591b on syzbot, and came to the conclusion that it is intended behaviour. The repro.c file was calling ioctl with the cmd as FBIOPUT_VSCREENINFO with an invalid yres (8) so the kernel was returning -EINVAL, from the function fbcon_modechange_possible. I am wondering is this intended behaviour, due to something happening on the user's end, or should it be something be implemented as a fallback? Thanks, Saad Varshani
