Hello all,

I have read the bug report now, and TBH I fail to see the security
problem here. If due to a crash I can still read old data from a file,
that just means that my recent attempt to remove/overwrite the data
from a file failed. Well, if the computer had crashed ten microseconds
earlier, and thus the disk wouldn't have managed to write the metadata
either, I would have the very same problem. Or did I misunderstood the
problem here?

I'd be very cautious to change something as fundamental as the file
system behaviour in an SRU. A crash fix is a valid SRU reason, but
this looks like a very intrusive change, not a focused bug fix to me.

Thanks,

Martin
