From 21176c0ae4ac9ab5ca7e1b7e6c234dee2a0022f0 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Tue, 27 Aug 2024 02:41:10 +0900 Subject: nilfs2: use the BITS_PER_LONG macro The macros NILFS_BMAP_KEY_BIT and NILFS_BMAP_NEW_PTR_INIT calculate, within their definitions, the number of bits in an unsigned long variable. Use the BITS_PER_LONG macro to make them simpler.
