You cannot move this line of code after dentry_iput(dentry); without considerations for locking.
Another thread can get this dentry and be changing dentry->d_flags at the same time! We have hit this in testing. The code must be changed to have locks (if this field needs to be changed or ...)
In our tests, the flag 0x10 in __d_drop goes missing because this line of code executed at the same time on another processor.
