Zach Brown f276795627 btrfs: fix btrfs_cont_expand() freeing IS_ERR em ... btrfs_cont_expand() tries to free an IS_ERR em as it gets an error from btrfs_get_extent() and breaks out of its loop. An instance of -EEXIST was reported in the wild: https://bugzilla.redhat.com/show_bug.cgi?id=874407 I have no idea if that -EEXIST is surprising, or not. Regardless, this error handling should be cleaned up to handle other reasonable errors (ENOMEM, EIO; whatever). This seemed to be the only buggy freeing of the relatively rare IS_ERR em so I opted to fix the caller rather than teach free_extent_map() to use IS_ERR_OR_NULL().
