Eric Whitney 0ca3768534 ext4: correct inline offset when handling xattrs in inode body ... commit 6909cf5c41 upstream. When run on a file system where the inline_data feature has been enabled, xfstests generic/269, generic/270, and generic/476 cause ext4 to emit error messages indicating that inline directory entries are corrupted. This occurs because the inline offset used to locate inline directory entries in the inode body is not updated when an xattr in that shared region is deleted and the region is shifted in memory to recover the space it occupied. If the deleted xattr precedes the system.data attribute, which points to the inline directory entries, that attribute will be moved further up in the region. The inline offset continues to point to whatever is located in system.data's former location, with unfortunate effects when used to access directory entries or (presumably) inline data in the inode body.
