"""

It seems like a bug in fs/inode.c.

The filesystem is ext4.
Core 2 Duo 3.0Ghz running Ubuntu Linux 11.04 with custom linux-3.0-rc3 kernel.

Comment 1 Ross Lagerwall 2011-06-16 07:48:00 UTC

The software is Octave 3.4.1 and running ./configure again reproduces the same thing.

Comment 2 Ross Lagerwall 2011-06-16 08:00:28 UTC

There appears to be a discussion on this at https://lkml.org/lkml/2011/6/10/520 along with a patch.

Comment 3 Florian Mickler 2011-06-17 11:25:54 UTC

Patch: https://patchwork.kernel.org/patch/883572/

Is somebody picking that patch up for merging to Linus?

Comment 4 Török Edwin 2011-06-17 11:32:03 UTC

Thanks, got merged already:
