io_ctl_map_page is called by many functions in free-space-cache.
In most scenarios, the ->cur is not null, e.g. io_ctl_add_entry.
I think we'd better remove the warn_on here.

btrfs can use generic_file_read_iter(). Base btrfs_file_write_iter()
on btrfs_file_aio_write(), then have the latter call the former.

Hello,
on a fs with 4 disks, raid 10 for data, one drive was failing and has
been removed. After reboot and 'mount -o degraded...', the fs looks
full, even though before removal of the failed device it was almost
80% free.
root@fs0:~# df -h /mnt/b
