I am paying very close attention to ext2 corruption reports, and have
been investigating a number on and off for a while. I've been doing
so since well before 1.0. However, we simply haven't seen any real
problems recently which weren't attributable, with _fairly_ high
certainty, to device driver or hardware problems. That's the trouble
with filesystems --- they depend on a whole stack of other components,
but if anything in that stack breaks it's often the filesystem itself
which gets blamed.

Having said that, there _does_ look like a definite problem in the VFS
inode.c as described in the latest thread, but even that shouldn't
affect filesystems in isolation --- it would only have any effect if
you were using non-filesystem inodes such as pipes and sockets in
addition to the filesystem itself.

You can't stall development just because some people are reporting
problems which are (a) not reproducible on other systems and (b) not
definitely identified as being the responsibility of any one component
in the system anyway. However, there _are_ people out here who pay
close attention to filesystem bug reports, so you are not being
