I am happy to review your proposed changes. Kostik's changes are needed in any
event as the kernel must protect against the deadlock and not just depend on a
utility to do so. However having the utility avoid the problem and give a more
specific error message is still good to have. Also the reordering to narrow the
window of vulnerability to filesystem corruption is much appreciated.
