nilfs2: add nilfs_sufile_trim_fs to trim clean segs

2014-04-03T23:21:25+00:00

Add nilfs_sufile_trim_fs(), which takes an fstrim_range structure and
calls blkdev_issue_discard for every clean segment in the specified
range.  The range is truncated to file system block boundaries.

nilfs2: add nilfs_sufile_set_suinfo to update segment usage

2014-04-03T23:21:25+00:00

Introduce nilfs_sufile_set_suinfo(), which expects an array of
nilfs_suinfo_update structures and updates the segment usage information
accordingly.

This is basically a helper function for the newly introduced
NILFS_IOCTL_SET_SUINFO ioctl.

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: get rid of mi_nilfs back pointer to nilfs object

structure that is attached to metadata files.

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.
