[Ocfs2-users] ocfs2_delete_inode kernel BUG

[Sunil Mushran]

Looks like a build issue in more ways than one.

kernel BUG at <bad filename>:33675!   ????


I suspect the location in clear_inode is:

if (inode->i_data.nrpages)
    BUG();

That means this is related to the 
truncate_inode_pages()/generic_delete_inode()
change introduced in 2.6.14.

Joel?
