Hi, all
The two patches can fix this problem.
ext4: Fix fs corruption when make_indexed_dir() fails
ext4: don't dereference null pointer when make_indexed_dir() fails
If any one comes across this problem, he can apply the above two patches.

OK. Thanks a lot.
This bug can happen on Ubuntu 11.04,10.10 with kernel 2.6.3x.
Follow the above steps, this bug can be reproduced.
Anyone has the same experience?

If I use kernel>=3.0, this will not occur.
Sounds like this is a problem in 2.6.39 that has since been fixed in
newer kernels.
So is this is a bug?
Sure looks like it's a bug. :-)
There are so many distributions and other old embedded systems, etc.,
using older kernels that there's just no way that upstream developers
can try to debug every single older kernel --- and 2.6.39 isn't even a
kernel that is being supported by a volunteer as a long-term supported
kernel.
See http://www.kernel.org for a list of kernels which are supported as
long-term kernels, and even then, please remember that unless fixes
are automatically backported, or someone manually backports a fix that
doesn't automatically apply to an older kernel, it's not going to
happen.....

P.S. Your problem appears to be completely unrelated to the thread
which you replied to. This makes it hard for us to keep track of
questions/bug reports which users submit.
