Zhoujie Wu 3f4f4c639f lightnvm: pblk: consider max hw sectors supported for max_write_pgs ... [ Upstream commit 8a57fc3823 ] When do GC, the number of read/write sectors are determined by max_write_pgs(see gc_rq preparation in pblk_gc_line_prepare_ws). Due to max_write_pgs doesn't consider max hw sectors supported by nvme controller(128K), which leads to GC tries to read 64 * 4K in one command, and see below error caused by pblk_bio_map_addr in function pblk_submit_read_gc.
