ubi: fastmap: Allocate memory with GFP_NOFS in ubi_update_fastmap
Function ubi_update_fastmap could be called in IO context, for example: ubifs_writepage do_writepage ubifs_jnl_write_data write_head ubifs_wbuf_write_nolock ubifs_leb_write ubi_leb_write ubi_eba_write_leb try_write_vid_and_data ubi_wl_get_peb ubi_update_fastmap erase_block So it's better to allocate memory with GFP_NOFS mode, in case waiting page writeback(dead loop).
