NFSD usess PAGE_SIZE as the reply size estimate for RPCs which don't support op_rsize_bop(), A PAGE_SIZE (4096) is larger than many real response sizes, eg, access (op_encode_hdr_size + 2), seek (op_encode_hdr_size + 3). This patch just adds op_rsize_bop() for all RPCs getting response size. An overestimate is generally safe but the tighter estimates are probably better.

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.
