Sorry my question was too vague. What I meant to ask is if it is possible, since there is a conflict between the locking requests from the kernel's NFS and from Gluster/fuse's NFS, that the kernel might be compiled so with some or all of its NFS support disabled, so that then Gluster/fuse NFS-locking would work. Perhaps longer term there needs to be a way to have the kernel shut its NFS locking attempts off, just if there is a userland NFS such as Gluster's running. Meanwhile can enough of NFS be taken out of a custom kernel to allow Gluster to lock?
