From: Toshiyuki Okajima <toshi.okajima@xxxxxxxxxxxxxx> commit b8b8afe236e97b6359d46d3a3f8c46455e192271 upstream (as of v2.6.33-git11) The callers of ext4_check_dir_entry() usually pass in the "file offset" (ext4_readdir, htree_dirblock_to_tree, search_dirblock, ext4_dx_find_entry, empty_dir), but a few callers (add_dirent_to_buf, ext4_delete_entry) only pass in the buffer offset. To accomodate those last two (which would be hard to fix otherwise), this patch changes ext4_check_dir_entry() to print the physical block number and the relative offset as well as the passed-in offset.
