nilfs2: get rid of NILFS_I_NILFS

2011-05-10T13:21:56+00:00

This replaces all references of NILFS_I_NILFS(inode)->ns_bdev with
inode->i_sb->s_bdev and unfolds remaining uses of NILFS_I_NILFS inline
function.

Before 2.6.37, referring to a nilfs object from inodes needed a
conditional judgement, and NILFS_I_NILFS was helpful to simplify it.
But now we can simply do it by going through a super block instance
like inode->i_sb->s_fs_info.

nilfs2: add ioctl which limits range of segment to be allocated

2011-05-10T13:21:45+00:00

This adds a new ioctl command which limits range of segment to be
allocated.  This is intended to gather data whithin a range of the
partition before shrinking the filesystem, or to control new log
location for some purpose.

If a range is specified by the ioctl, segment allocator of nilfs tries
to allocate new segments from the range unless no free segments are
available there.

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.

nilfs2: clean up get/put function of a segment usage

2009-11-20T01:05:51+00:00

This eliminates obsolete nilfs_get_sufile_get_segment_usage() and
nilfs_set_sufile_segment_usage() from sufile.

nilfs2: move routine to set segment usage into sufile

2009-11-20T01:05:51+00:00

This adds nilfs_sufile_set_segment_usage() function in sufile to
replace direct access to the sufile metadata in log writer code.

nilfs2: move routine marking segment usage dirty into sufile

2009-11-20T01:05:51+00:00

This adds nilfs_sufile_mark_dirty() function in sufile to replace
nilfs_touch_segusage() function in log writer code.  This is a
preparation for the further cleanup which will move out low level
sufile operations in the log writer.

nilfs2: simplify nilfs_sufile_get_ncleansegs function

2009-11-20T01:05:49+00:00

Previously, this function took an status code to return possible error
codes.  The ("nilfs2: add local variable to cache the number of clean
segments") patch removed the possibility to return errors.

So, this simplifies the function definition to make it directly return
the number of clean segments.

nilfs2: separate read method of meta data files on super root block

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

Will displace nilfs_mdt_read_inode_direct function with an individual
read method: nilfs_dat_read, nilfs_sufile_read, nilfs_cpfile_read.

This provides the opportunity to initialize local variables of each
metadata file after reading the inode.
