ac27a0ec112a089 Dave Kleikamp 2006-10-11 5249 * shrinks i_size, we put the inode on the orphan list and modify
ac27a0ec112a089 Dave Kleikamp 2006-10-11 5250 * i_disksize immediately, so that during the subsequent flushing of
ac27a0ec112a089 Dave Kleikamp 2006-10-11 5251 * dirty pages and freeing of disk blocks, we can guarantee that any

ac27a0ec112a089 Dave Kleikamp 2006-10-11 5253 * disk. (On recovery, the inode will get truncated and the blocks will
ac27a0ec112a089 Dave Kleikamp 2006-10-11 5254 * be freed, so we have a strong guarantee that no future commit will
ac27a0ec112a089 Dave Kleikamp 2006-10-11 5255 * leave these blocks visible to the user.)
