nit: the commit title refers to ceph_open() but the code changes are pertaining to ceph_lookup() Otherwise it looks good to me.

I couldn't remember why we didn't fix this before as I remembered I have found this.

Yeah, it's really odd we didn't catch this before. I had to go look at old email: this helper was initially used in ceph_atomic_open() only, but then in v3 it was made more generic so that it could also be used in ceph_lookup(). Xiubo, do you want me to send out a new version of this patch, or are you OK simply updating the subject, using 'ceph_lookup' instead of 'ceph_open'? Cheers,

No worry, I have fixed this in the 'testing' branch and I will send out the v20 for this whole series later. Thank - Xiubo > Cheers,
