nilfs2: use mark_buffer_dirty to mark btnode or meta data dirty

2011-05-10T13:21:57+00:00

This replaces nilfs_mdt_mark_buffer_dirty and nilfs_btnode_mark_dirty
macros with mark_buffer_dirty and gets rid of nilfs_mark_buffer_dirty,
an own mark buffer dirty function.

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 truncation routine of segment usage file

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

When shrinking the filesystem, segments to be truncated must be test
if they are busy or not, and unneeded sufile block should be deleted.
This adds routines for the truncation.

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: move routine to set segment usage into sufile

replace direct access to the sufile metadata in log writer code.
