By the time we start processing the orphan inode list, we have already calculated the total expected number of free blocks and inodes in ctx->free_{blocks,inodes}. This is used to set the free blocks/inodes count in the superblock in the case where we don't need to do a full e2fsck. We need to update these expected free block counts as we process the orphan inode list so that superblock values are set correctly. Otherwise we could have the following happen: % e2fsck /tmp/test.img e2fsck 1.42.3 (14-May-2012) Truncating orphaned inode 12 (uid=0, gid=0, mode=0100644, size=0) Setting free blocks count to 46 (was 79) /tmp/test.img: clean, 12/16 files, 54/100 blocks % e2fsck /tmp/test.img e2fsck 1.42.3 (14-May-2012) Setting free blocks count to 79 (was 46) /tmp/test.img: clean, 12/16 files, 21/100 blocks Signed-off-by: "Theodore Ts'o" <tytso@xxxxxxx> --- e2fsck/super.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/e2fsck/super.c b/e2fsck/super.c index 6c18d0e..160991d 100644 --- a/e2fsck/super.c +++ b/e2fsck/super.c @@ -143,6 +143,7 @@ static int release_inode_block(ext2_filsys fs, } ext2fs_block_alloc_stats2(fs, blk, -1); + ctx->free_blocks++; return retval; } @@ -211,9 +212,11 @@ static int release_inode_blocks(e2fsck_t ctx, ext2_ino_t ino, ino); return 1; } - if (count == 0) + if (count == 0) { ext2fs_block_alloc_stats2(fs, ext2fs_file_acl_block(fs, inode), -1); + ctx->free_blocks++; + } ext2fs_file_acl_block_set(fs, inode, 0); } return 0; @@ -286,6 +289,7 @@ static int release_orphan_inodes(e2fsck_t ctx) if (!inode.i_links_count) { ext2fs_inode_alloc_stats2(fs, ino, -1, LINUX_S_ISDIR(inode.i_mode)); + ctx->free_inodes++; inode.i_dtime = ctx->now; } else { inode.i_dtime = 0; -- 1.7.10.2.552.gaa3bb87 -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
