@Rocko,

If you really want this, you can disable delayed allocation via the
mount option, "nodelalloc".  You will take a performance hit and your
files will be more fragmented.   But if you have applications which
don't call fsync(), and you have an unstable system, then you can use
the mount option.   All I can say is that I don't see these data loss
problems, but everyone has different usage patterns.

In terms of trashed object files in the middle of the build, those
object files are non-precious files.   How often do you crash in the
middle of a build?  Should you slow down all builds just to handle the
rare case where your system crashes in the middle of the build?   Or
would it be better to run "make clean", and rebuild the tree in the case
where you have trashed object files?   It's not like a kernel rebuild
takes that long.  OTOH, if your system is crashing all the time, there's
something else seriously wrong; Linux systems shouldn't be that
unstable.
