From bccb5c397fbfe348e22c045f5e09c35780edb817 Mon Sep 17 00:00:00 2001 From: Luca Vizzarro Date: Thu, 2 Feb 2023 11:58:31 +0000 Subject: fcntl: Cast commands with int args explicitly According to the fcntl API specification commands that expect an integer, hence not a pointer, always take an int and not long. In order to avoid access to undefined bits, we should explicitly cast the argument to int.
