vm_page_fault KDL when removing files on an ext2 volume

[v.vill]

Greetings,
I've noticed that removing inodes with the ext2 driver tends to trigger a KDL. Here's how I do it:

~> dd if=/dev/zero bs=1024 count=250000 of=/unnamed\ volume/test
250000+0 records in
250000+0 records out
256000000 bytes (256 MB, 244 MiB) copied, 15,3417 s, 16,7 MB/s
~> mv /unnamed\ volume/test ./
~> mv ./test /unnamed\ volume/

The KDL is triggered when I repeat the last two commands a couple of times.

I'm using an ext4 volume formatted with standard options, on hrev52365 x86_64.

Ha, it's a duplicate of your own ticket! :-P

Oh, indeed! I didn’t remember reporting this one (I was thinking about #11407 which I reported much earlier on, with regard to NTFS partitions). Nice catch.
