From 5272f8372786a181313c00c7a67304ac6def2e34 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 16 Oct 2007 18:38:25 -0400 Subject: ext4: Convert bg_inode_bitmap and bg_inode_table Convert bg_inode_bitmap and bg_inode_table to bg_inode_bitmap_lo and bg_inode_table_lo. This helps in finding BUGs due to direct partial access of these split 64 bit values Also fix one direct partial access Signed-off-by: Aneesh Kumar K.V --- fs/ext4/super.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'fs/ext4/super.c') diff --git a/fs/ext4/super.c b/fs/ext4/super.c index 1e8eaaf2d4a5..f9cb64c5010b 100644 --- a/fs/ext4/super.c +++ b/fs/ext4/super.c @@ -78,17 +78,17 @@ ext4_fsblk_t ext4_block_bitmap(struct super_block *sb, ext4_fsblk_t ext4_inode_bitmap(struct super_block *sb, struct ext4_group_desc *bg) { - return le32_to_cpu(bg->bg_inode_bitmap) | + return le32_to_cpu(bg->bg_inode_bitmap_lo) | (EXT4_DESC_SIZE(sb) >= EXT4_MIN_DESC_SIZE_64BIT ? - (ext4_fsblk_t)le32_to_cpu(bg->bg_inode_bitmap_hi) << 32 : 0); + (ext4_fsblk_t)le32_to_cpu(bg->bg_inode_bitmap_hi) << 32 : 0); } ext4_fsblk_t ext4_inode_table(struct super_block *sb, struct ext4_group_desc *bg) { - return le32_to_cpu(bg->bg_inode_table) | + return le32_to_cpu(bg->bg_inode_table_lo) | (EXT4_DESC_SIZE(sb) >= EXT4_MIN_DESC_SIZE_64BIT ? - (ext4_fsblk_t)le32_to_cpu(bg->bg_inode_table_hi) << 32 : 0); + (ext4_fsblk_t)le32_to_cpu(bg->bg_inode_table_hi) << 32 : 0); } void ext4_block_bitmap_set(struct super_block *sb, @@ -102,7 +102,7 @@ void ext4_block_bitmap_set(struct super_block *sb, void ext4_inode_bitmap_set(struct super_block *sb, struct ext4_group_desc *bg, ext4_fsblk_t blk) { - bg->bg_inode_bitmap = cpu_to_le32((u32)blk); + bg->bg_inode_bitmap_lo = cpu_to_le32((u32)blk); if (EXT4_DESC_SIZE(sb) >= EXT4_MIN_DESC_SIZE_64BIT) bg->bg_inode_bitmap_hi = cpu_to_le32(blk >> 32); } @@ -110,7 +110,7 @@ void ext4_inode_bitmap_set(struct super_block *sb, void ext4_inode_table_set(struct super_block *sb, struct ext4_group_desc *bg, ext4_fsblk_t blk) { - bg->bg_inode_table = cpu_to_le32((u32)blk); + bg->bg_inode_table_lo = cpu_to_le32((u32)blk); if (EXT4_DESC_SIZE(sb) >= EXT4_MIN_DESC_SIZE_64BIT) bg->bg_inode_table_hi = cpu_to_le32(blk >> 32); } -- cgit v1.2.2
