Subject: [PATCH v2.6.32.y 21/53] ext4: make "offset" consistent in ext4_check_dir_entry()
Date: Sun, 30 May 2010 22:49:34 -0400	[thread overview]
Message-ID: <1275274206-3900-21-git-send-email-tytso@mit.edu> (raw)
In-Reply-To: <1275274206-3900-1-git-send-email-tytso@mit.edu>

From: Toshiyuki Okajima <toshi.okajima@jp.fujitsu.com>

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.
