/*
* NILFS2 needs clear_page_dirty() in the following two cases:
*
- * 1) For B-tree node pages and data pages of the dat/gcdat, NILFS2 clears
- * page dirty flags when it copies back pages from the shadow cache
- * (gcdat->{i_mapping,i_btnode_cache}) to its original cache
- * (dat->{i_mapping,i_btnode_cache}).
+ * 1) For B-tree node pages and data pages of DAT file, NILFS2 clears dirty
+ * flag of pages when it copies back pages from shadow cache to the
+ * original cache.
*
* 2) Some B-tree operations like insertion or deletion may dispose buffers
* in dirty state, and this needs to cancel the dirty state of their pages.
