* NFS: Add COPY nfs operationAnna Schumaker2016-05-171-0/+1
| | | | | | | | This adds the copy_range file_ops function pointer used by the sys_copy_range() function call. This patch only implements sync copies, so if an async copy happens we decode the stateid and ignore it. Signed-off-by: Anna Schumaker <bjschuma@netapp.com>

* NFS: Implement SEEKAnna Schumaker2014-09-301-0/+14
The SEEK operation is used when an application makes an lseek call with either the SEEK_HOLE or SEEK_DATA flags set. I fall back on nfs_file_llseek() if the server does not have SEEK support.
