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.Link: http://lkml.kernel.org/r/1461935747-10380-4-git-send-email-konishi.ryusuke@lab.ntt.co.jp

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 adds a field to record the latest checkpoint number in the
nilfs_segment_summary structure. This will help to recover the latest
checkpoint number from logs on disk. This field is intended for
crucial cases in which super blocks have lost pointer to the latest
log.Even though this will change the disk format, both backward and
forward compatibility is preserved by a size field prepared in the
segment summary header.Signed-off-by: Ryusuke Konishi

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 moves iterator to submit write requests for a series of logs into
segbuf.c, and hides nilfs_segbuf_write() and nilfs_segbuf_wait() in
the file.Signed-off-by: Ryusuke Konishi

This separates wait function for submitted logs from the write
function nilfs_segctor_write(). A new list of segment buffers
"sc_write_logs" is added to hold logs under writing, and double
buffering is partially applied to hide io latency.At this point, the double buffering is disabled for blocksize <
pagesize because page dirty flag is turned off during write and dirty
buffers are not properly collected for pages crossing over segments.To receive full benefit of the double buffering, further refinement is
needed to move the io wait outside the lock section of log writer.Signed-off-by: Ryusuke Konishi

This adds a few iterator functions for segment buffers to make it easy

Hides nilfs_write_info struct and nilfs_segbuf_prepare_write function

This moves io status variables in nilfs_write_info struct to
nilfs_segment_buffer struct.This is a preparation to hide nilfs_write_info in segment buffer code.

will reduce some lines of segment constructor. Previously, the state was
complexly controlled through a list of segments in order to keep
consistency in meta data of usage state of segments. Instead, this
presents ``calculated'' active flags to userland cleaner program and stop
maintaining its real flag on disk.Only by this fake flag, the cleaner cannot exactly know if each segment is
reclaimable or not. However, the recent extension of nilfs_sustat ioctl
struct (nilfs2-extend-nilfs_sustat-ioctl-struct.patch) can prevent the
cleaner from reclaiming in-use segment wrongly.So, now I can apply this for simplification.
