nilfs2: implement calculation of free inodes count

2013-07-03T23:08:01+00:00

Currently, NILFS2 returns 0 as free inodes count (f_ffree) and current used inodes count as total file nodes in file system (f_files): df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/loop0 2 2 0 100% /mnt/nilfs2 This patch implements real calculation of free inodes count. First of all, it is calculated total file nodes in file system as (desc_blocks_count * groups_per_desc_block * entries_per_group). Then, it is calculated free inodes count as difference the total file nodes and used inodes count. As a result, we have such output for NILFS2: df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/loop0 4194304 2114701 2079603 51% /mnt/nilfs2 Reported-by: Clemens Eisserer Signed-off-by: Vyacheslav Dubeyko Signed-off-by: Ryusuke Konishi Tested-by: Vyacheslav Dubeyko Cc: Joern Engel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

nilfs2: use iget for all metadata files

2010-10-23T00:24:38+00:00

This makes use of iget5_locked to allocate or get inode for metadata files to stop using own inode allocator. Signed-off-by: Ryusuke Konishi

nilfs2: separate constructor of metadata files

2009-11-20T01:05:48+00:00

This will displace nilfs_mdt_new() constructor with individual metadata file constructors like nilfs_dat_new(), new_sufile_new(), nilfs_cpfile_new(), and nilfs_ifile_new(). This makes it possible for each metadata file to have own intialization code. Signed-off-by: Ryusuke Konishi

nilfs2: remove individual gfp constants for each metadata file

2009-09-14T09:27:15+00:00

This gets rid of NILFS_CPFILE_GFP, NILFS_SUFILE_GFP, NILFS_DAT_GFP, and NILFS_IFILE_GFP. All of these constants refer to NILFS_MDT_GFP, and can be removed. Signed-off-by: Ryusuke Konishi

nilfs2: inode map file

2009-04-07T15:31:14+00:00

This adds a meta data file which stores on-disk inodes in its data blocks. Signed-off-by: Ryusuke Konishi Signed-off-by: Yoshiji Amagai Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
