If anyone has any objections, please let me know. ------------------ From: Bart Van Assche [ Upstream commit edf57cbf2b030781885e339f32e35a470d2f8eba ] The C programming language does not allow to use preprocessor statements inside macro arguments (pr_info() is defined as a macro). Hence rework the pr_info() statement in btrfs_print_mod_info() such that it becomes compliant. This patch allows tools like sparse to analyze the BTRFS source code.
