Hi!
In this case O_EXCL is going to be more accurate just because the
mounted check doesn't cover every disk in the FS. For now btrfsck
doesn't really give consistent results even readonly on a mounted
filesystem. We should prevent it with a message just to prevent
confusion.
Thanks
Just open the nodes with O_EXCL and you'll get all the checking for
free. Also make sure that for a pure, read-only checks instead of a
repair to allow running on at least a read-only mounted filesystem.
Thanks for working on this patch Andi.
