Both writing a mounted device and writing part0 while mounting a
partition will provide a prompt message.

v1->v2:

1. Replace BLK_DEV_DUMPINFO with BLK_DEV_WRITE_MOUNTED_QUIET, which is
   logically opposite;
2. Make BLK_DEV_WRITE_MOUNTED_QUIET dependent on
   BLK_DEV_WRITE_MOUNTED, and decide whether to set bd_writers
   by BLK_DEV_WRITE_MOUNTED_QUIET;
3. Move bdev_dump_info() into bdev_may_open();
4. Add the cmdline interface to control whether to show info;
5. Pass the state of "writes blocked" to part0 when mounting a
   partition.

Li Lingfeng (3):
block: Add config to show info about opening a mounted device for
write
block: detect confilt of write and mount between partitions and part0
block: show info of confilt of write and mount between partitions and
part0
