* nilfs2: replace nilfs_warning() with nilfs_msg()Ryusuke Konishi2016-08-021-2/+2
| | | | | | | | | | | | | | Use nilfs_msg() to output warning messages and get rid of nilfs_warning() function. This also removes function names from the messages unless we embed them explicitly in format strings. Instead, some messages are revised to clarify the context.

* nilfs2: hide function name argument from nilfs_error()Ryusuke Konishi2016-08-021-2/+1
| | | | | | | | | | | | | | | | Simplify nilfs_error(), an output function used to report critical issues in file system. This renames the original nilfs_error() function to __nilfs_error() and redefines it as a macro to hide its function name argument within the macro. Every call site of nilfs_error() is changed to strip __func__ argument except nilfs_bmap_convert_error(); nilfs_bmap_convert_error() directly calls __nilfs_error() because it inherits caller's function name.

* ] nilfs2: use atomic64_t type for inodes_count and blocks_count fields in ↵Vyacheslav Dubeyko2013-07-031-1/+1
| | | | | | | | | | | | | | | | | | 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.

* nilfs2: implement calculation of free inodes countVyacheslav Dubeyko2013-07-031-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <linuxhippy@gmail.com> Signed-off-by: Vyacheslav Dubeyko <slava@dubeyko.com> Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Tested-by: Vyacheslav Dubeyko <slava@dubeyko.com> Cc: Joern Engel <joern@logfs.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* nilfs2: use mark_buffer_dirty to mark btnode or meta data dirtyRyusuke Konishi2011-05-101-2/+2
| | | | | | | | This replaces nilfs_mdt_mark_buffer_dirty and nilfs_btnode_mark_dirty macros with mark_buffer_dirty and gets rid of nilfs_mark_buffer_dirty, an own mark buffer dirty function. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
* nilfs2: call nilfs_error inside bmap routinesRyusuke Konishi2011-01-101-8/+3
| | | | | | | | | | | Some functions using nilfs bmap routines can wrongly return invalid argument error (i.e. -EINVAL) that bmap returns as an internal code for btree corruption. This fixes the issue by catching and converting the internal EINVAL to EIO and calling nilfs_error function inside bmap routines. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
* nilfs2: use iget for all metadata filesRyusuke Konishi2010-10-231-15/+36

* nilfs2: add palloc cache to ifileRyusuke Konishi2009-11-201-1/+15
| | | | | | | | This adds the palloc cache to ifile. The palloc cache is allocated on the extended region of nilfs_mdt_info struct. The struct nilfs_ifile_info defines the extended on memory structure of ifile. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
* nilfs2: separate constructor of metadata filesRyusuke Konishi2009-11-201-0/+21
| | | | | | | | | | | 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 <konishi.ryusuke@lab.ntt.co.jp>
