This removes nilfs_bmap_union and finally unifies three structures and
the union in bmap/btree code into one.Signed-off-by: Ryusuke Konishi
-
This replaces all uses of nilfs_btree struct in implementation of
btree mapping with nilfs_bmap struct.Name of local variable "btree" is kept not to bloat amount of change.
And, a part of local variables "bmap" is renamed to "btree" to uniform
naming rule.Signed-off-by: Ryusuke Konishi

This inserts sanity checks soon after read btree node from disk. This
allows early detection of broken btree nodes, and helps to narrow down
problems due to file system corruption.Signed-off-by: Ryusuke Konishi

The commit 41c88bd7 ("nilfs2: cleanup multi
kmem_cache_{create,destroy} code") consolidated slab constructors and
destructors used in nilfs, but it left some declarations in header
files.This gets rid of the obsolete declarations.

This cleanup patch gives several improvements:
- Moving all kmem_cache_{create_destroy} calls into one place, which removes
some small function calls, cleans up error check code and clarify the logic.- Mark all initial code in __init section.
- Remove some very obvious comments.
- Adjust some declarations.
- Fix some space-tab issues.

This is a trivial patch to expose struct nilfs_fs_btree_node.
The struct should be exposed outside of kernel, for it is disk format.Signed-off-by: Jiro SEKIBA

will remove indirect function calls using nilfs_btree_operations
table.Signed-off-by: Ryusuke Konishi

This will cut off 16 bytes from the nilfs_bmap struct which is
embedded in the on-memory inode of nilfs.The b_high field was never used, and the b_low field stores a constant
value which can be determined by whether the inode uses btree for
block mapping or not.Signed-off-by: Ryusuke Konishi

This adds declarations and functions of NILFS2 B-tree.
Two variants are integrated in the NILFS2 B-tree. The B-tree for the most
files points to the child nodes or data blocks with virtual block
addresses, whereas the B-tree of the DAT uses actual block addresses.Signed-off-by: Koji Sato
