However, i_data also seems to be used for truncate_inode_pages. What exactly is the logical difference between the two and when does one need to maek the distinction between the two pointers? Any pointers or information would be most helpful Thanks ________________________________________________ Get your own "800" number Voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
