Hi,
I am going on holiday for two weeks from tomorrow but when I get back I
will backport the new allocator from ntfs tng to the old ntfs driver. This
only uses vmalloc if necessary so will decrease the number of vmalloc()s
dramatically and hopefully this will make your kernel happier.
I will CC: patch to you so you can see if all your problems go away or if
it is not sufficient.
Best regards,
Anton
