* nilfs2: insert explanations in gcinode fileRyusuke Konishi2009-04-071-1/+20
| | | | | | | | | | | | | | | The file gcinode.c gives buffer cache functions for on-disk blocks moved in garbage collection. Joern Engel has suggested inserting its explanations in the source file (Message-ID: <20080917144146.GD8750@logfs.org> and <20080917224953.GB14644@logfs.org>). This follows the comment.

* nilfs2: block cache for garbage collectionRyusuke Konishi2009-04-071-0/+270
This adds the cache of on-disk blocks to be moved in garbage collection. The disk blocks are held with dummy inodes (called gcinodes), and this file provides lookup function of the dummy inodes, and their buffer read function.
