I can't find any code outside of ceph where the dcache_lock is used
within 200 lines of code of the inode->i_lock. The ceph code is not
nesting them, though. And AFAICT, the i_lock is not used at all in the
dentry code.

So I must be missing something if this is occurring - can you point
out where this lock ordering is occurring in the mainline code?

Cheers,

Dave.
