So now you've removed Gavin Shan who already told you that it was correct 
as written and propose yet another bogus patch which will break.  This 
isn't professional.

alloc_inode() tests for a NULL return value, not for PTR_ERR(), so you 
would be introducing a bug if this patch were merged.  It's completely 
correct the way it's written.
