 Basic on-flash UBIFS entities are called *nodes*. UBIFS knows different types
-of nodes. Eg. data nodes (`struct ubifs_data_node`) which store chunks of file
-contents or inode nodes (`struct ubifs_ino_node`) which represent VFS inodes.
-Almost all types of nodes share a common header (`ubifs_ch`) containing basic
+of nodes. Eg. data nodes (``struct ubifs_data_node``) which store chunks of file

+Almost all types of nodes share a common header (``ubifs_ch``) containing basic
 information like node type, node length, a sequence number, etc. (see

+``fs/ubifs/ubifs-media.h`` in kernel source). Exceptions are entries of the LPT
 and some less important node types like padding nodes which are used to pad
 unusable content at the end of LEBs.
