-+What: /debug/aufs/si_<id>/
-+Date: March 2009
-+Contact: J. R. Okajima <hooanon05 at yahoo.co.jp>
-+Description:
-+ Under /debug/aufs, a directory named si_<id> is created
-+ per aufs mount, where <id> is a unique id generated
-+ internally.
-+
-+What: /debug/aufs/si_<id>/xib
-+Date: March 2009
-+Contact: J. R. Okajima <hooanon05 at yahoo.co.jp>
-+Description:
-+ It shows the consumed blocks by xib (External Inode Number
-+ Bitmap), its block size and file size.
-+ When the aufs mount option 'noxino' is specified, it
-+ will be empty. About XINO files, see the aufs manual.
-+
-+What: /debug/aufs/si_<id>/xino0, xino1 ... xinoN
-+Date: March 2009
-+Contact: J. R. Okajima <hooanon05 at yahoo.co.jp>
-+Description:
-+ It shows the consumed blocks by xino (External Inode Number
-+ Translation Table), its link count, block size and file
-+ size.
-+ When the aufs mount option 'noxino' is specified, it
-+ will be empty. About XINO files, see the aufs manual.
-+
-+What: /debug/aufs/si_<id>/xigen
-+Date: March 2009
-+Contact: J. R. Okajima <hooanon05 at yahoo.co.jp>
-+Description:
-+ It shows the consumed blocks by xigen (External Inode
-+ Generation Table), its block size and file size.
-+ If CONFIG_AUFS_EXPORT is disabled, this entry will not
-+ be created.
-+ When the aufs mount option 'noxino' is specified, it
-+ will be empty. About XINO files, see the aufs manual.
