nfsd: Revert "nfsd: special case truncates some more"
This patch incorrectly attempted nested mnt_want_write, and incorrectly disabled nfsd's owner override for truncate. We'll fix those problems and make another attempt soon, for the moment I think the safest is to revert. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

ts the latest translations from the OS when pages are not present, and the OS invalidates translations which are no longer valid due to either non-present pages or mapping changes. In existing ODP implementation applications is needed to register memory buffers for communication, though registered memory regions need not have valid mappings at registration time. This patch set performs the following steps to expand current ODP implementation: 1. It refactors UMR to support large regions, by introducing generic function to perform HCA translation table modifications. This function supports both atomic and process contexts and is not limited by number of modified entries. This function allows to enable reallocated memory regions of arbitrary size, so adding MR cache buckets to support up to 16GB MRs. 2. It changes page fault event format and refactor page faults logic together with addition of atomic support. 3. It prepares mlx5 core code to support implicit registration with simplified and relaxed semantics. Implicit ODP semantics allows to applications provide special memory key that represents their complete address space. Thus all IO accesses referencing to this key (with proper access rights associated with the key) wouldn't need not register any virtual address range.
