+ * ext2fs.h: Remove definition of ext2fs_sb. Note: this may break
+ source (but not binary) compatibility of some users of the
+ ext2 library. They should just simply do a global search
+ and replace of struct ext2fs_sb with struct
+ ext2_super_block, and use their own private copy of
+ ext2_fs.h if they aren't already.
+
+ * closefs.c, initialize.c, link.c, newdir.c, openfs.c, swapfs.c:
+ Replace use of ext2fs_sb with ext2_super_block.
