xfs: format logged extents directly into the CIL
With the new iop_format scheme there is no need to have a temporary buffer
to format logged extents into, we can do so directly into the CIL. This
also allows to remove the shortcut for big endian systems that probably
hasn't gotten a lot of test coverage for a long time.

- * xfs_iextents_copy()
+ * Convert in-core extents to on-disk form
*
- * This is called to copy the REAL extents (as opposed to the delayed
- * allocation extents) from the inode into the given buffer. It
- * returns the number of bytes copied into the buffer.
+ * For either the data or attr fork in extent format, we need to endian convert
+ * the in-core extent as we place them into the on-disk inode.
*
- * If there are no delayed allocation extents, then we can just
- * memcpy() the extents into the buffer. Otherwise, we need to
- * examine each extent in turn and skip those which are delayed.
+ * In the case of the data fork, the in-core and on-disk fork sizes can be
+ * different due to delayed allocation extents. We only copy on-disk extents
+ * here, so callers must always use the physical fork size to determine the
+ * size of the buffer passed to this routine. We will return the size actually
+ * used.
