DLM portion of commit 16e5c1fc needs reverting or fixing "convert a bunch of open-coded instances of memdup_user_nul()"

Hi,

Al, this change to fs/dlm/user.c is wrong and needs fixing:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/fs/dlm/user.c?id=16e5c1fc36040e592128a164499bc25eb138a80f

There are two things:
- It uses !IS_ERR() where it should use IS_ERR()
- It doesn't set GFP_NOFS

Can you fix it please? Or do you want me to post a patch? You might want to check the other changes in the set for similar things.

Regards,
