ext2: Avoid loading bitmaps for full groups during block allocation There is no point in loading bitmap for groups which are completely full. This causes noticeable performance problems (and memory pressure) on small systems with large full filesystem (http://marc.info/?l=linux-ext4&m=126843108314310&w=2). Port of the same ext3 patch.
