Ryusuke Konishi ae98043f5f nilfs2: convert to SPDX license tags
Remove the verbose license text from NILFS2 files and replace them with
SPDX tags.  This does not change the license of any of the code.

Ryusuke Konishi e63e88bc53 nilfs2: move ioctl interface and disk layout to uapi separately
The header file "include/linux/nilfs2_fs.h" is composed of parts for
ioctl and disk format, and both are intended to be shared with user
space programs.

This moves them to the uapi directory "include/uapi/linux" splitting the
file to "nilfs2_api.h" and "nilfs2_ondisk.h".  The following minor
changes are accompanied by this migration:

 - nilfs_direct_node struct in nilfs2/direct.h is converged to
   nilfs2_ondisk.h because it's an on-disk structure.
 - inline functions nilfs_rec_len_from_disk() and
   nilfs_rec_len_to_disk() are moved to nilfs2/dir.c.

Ryusuke Konishi 4b420ab4ee nilfs2: clean up old e-mail addresses
E-mail addresses of osrg.net domain are no longer available.  This
removes them from authorship notices and prevents reporters from being
confused.

Ryusuke Konishi 5726d0b454 nilfs2: remove FSF mailing address from GPL notices
This removes the extra paragraph which mentions FSF address in GPL
notices from source code of nilfs2 and avoids the checkpatch.pl error
related to it.

Ryusuke Konishi e7c274f808 nilfs2: get rid of nilfs_btree uses
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.

Ryusuke Konishi 1d5385b9f3 nilfs2: verify btree node after reading
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.

Ryusuke Konishi c29684d683 nilfs2: remove obsolete declarations of cache constructor and destructor
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.

Li Hong 41c88bd74d nilfs2: cleanup multi kmem_cache_{create,destroy} code
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.

Jiro SEKIBA 6600b9dd8e nilfs2: move definition of struct nilfs_btree_node
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.

Ryusuke Konishi 3033342a0b nilfs2: remove useless b_low and b_high fields from nilfs_bmap struct
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.

Koji Sato 17c76b0104 nilfs2: B-tree based block mapping
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.
