Bug#347933: 2.6.15-2-686: kernel BUG at fs/inode.c:252

[Jurij Smakov]

Hi,

It looks like the reason for this bug might be the recent change in 
fs/inode.c [0]. According to the comments in this patch, the filesystems 
which implement the delete_inode callback must now also call 
truncate_inode_pages before clearing the inode. The attached patch 
implements this change. I was only able to make sure that modified lufs 
kernel module builds and loads, it would be great if someone would do some 
real-life testing with it.
