But, can we remove this bi_private allocation? This patch removes such the additional bi_private allocation. 1. Retrieve f2fs_sb_info from its page->mapping->host->i_sb. - This removes the usecases of bi_private in end_io. 2. Use bi_private only when we really need it. - The bi_private is used only when the checkpoint procedure is conducted. - When conducting the checkpoint, f2fs submits a META_FLUSH bio to wait its bio completion. - Since we have no dependancies to remove bi_private now, let's just use bi_private pointer as the completion pointer.
