staging: erofs: add erofs_map_blocks_iter 2018-07-27T15:24:08+00:00 Gao Xiang gaoxiang25@huawei.com 2018-07-26T12:21:58+00:00 02827e1796b33f1794966f5c3101f8da2dfa9c1d This patch introduces an iterable L2P mapping operation 'erofs_map_blocks_iter'. Compared with 'erofs_map_blocks', it avoids a number of redundant 'release and regrab' processes if they request the same meta page.
