nilfs2: return EBUSY against delete request on snapshot This helps userland programs like the rmcp command to distinguish error codes returned against a checkpoint removal request. Previously -EPERM was returned, and not discriminable from real permission errors. This also allows removal of the latest checkpoint because the deletion leads to create a new checkpoint, and thus it's harmless for the filesystem.
