NFSv4 write compound processing invokes nfsd_vfs_write directly. The trace points currently in nfsd_write are not effective for NFSv4 writes. Move the trace points into the shared nfsd_vfs_write() helper. After the I/O, we also want to record any local I/O error that might have occurred, and the total count of bytes that were actually moved (rather than the requested number).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
