--- Comment #20 from Kirk McKusick <mckusick@FreeBSD.org> ---
(In reply to Damjan Jovanovic from comment #19)
You are correct in what the code needs to do. The general areas that are li=
kely
to be problematic are when a write fails and when a file is deleted. For wr=
ite
failures the UFS strategy is to deallocate and invalidate the block. When a
file is deleted, any of its in-memory data needs to be freed so that it does
not "reappear" if the file once again is written.
