Mateusz,

Just want to mention explicitly that in addition to the lockless lookup 
changes that you suggested in [1], the test run also included your other 
commit 
https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/commit/?h=vfs.inode.rcu&id=7180f8d91fcbf252de572d9ffacc945effed0060 
as you had suggested.

Regards,
Bharata.
