From ed4422e98ababf956674da3438ac42b3aa32c66e Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Wed, 10 May 2023 00:41:06 +0200 Subject: [PATCH] Fix compilation warning with 64 bit system Use %zu and %zd where possible for ssize_t and size_t. Use PTR_ERR to correctly convert to negative error. Use universal pointer to support both 32 and 64bit systems.
