From e5f7f84843154db8b6ef5b2ac5e286f72212f54e Mon Sep 17 00:00:00 2001 From: Vyacheslav Dubeyko Date: Wed, 3 Jul 2013 15:08:06 -0700 Subject: ] nilfs2: use atomic64_t type for inodes_count and blocks_count fields in nilfs_root struct The cp_inodes_count and cp_blocks_count are represented as __le64 type in on-disk structure (struct nilfs_checkpoint). But analogous fields in in-core structure (struct nilfs_root) are represented by atomic_t type. This patch replaces atomic_t on atomic64_t type in representation of inodes_count and blocks_count fields in struct nilfs_root.
