From ed5f17f66ef39273dcf83ca89b2f1d52a52b22a5 Mon Sep 17 00:00:00 2001 From: Luca Vizzarro Date: Wed, 1 Feb 2023 15:05:33 +0000 Subject: fs: Pass argument to fcntl_setlease as int The interface for fcntl expects the argument passed for the command F_SETLEASE to be of type int. The current code wrongly treats it as a long. In order to avoid access to undefined bits, we should explicitly cast the argument to int.
