Its filename was ipc-fix-compat-msgrcv-with-negative-msgtyp.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mateusz Guzik <mguzik@xxxxxxxxxx> Subject: ipc: fix compat msgrcv with negative msgtyp Compat function takes msgtyp argument as u32 and passes it down to do_msgrcv which results in casting to long, thus the sign is lost and we get a big positive number instead. Cast the argument to signed type before passing it down.
