This patch dropped support for remote entry statahead, because it needs 2 async RPCs to fetch both LOOKUP lock from parent MDT and UPDATE lock from client MDT, which is complicated. Plus not supporting remote entry statahead won't cause any issue. * pack child fid in statahead request. * lmv_intent_getattr_async() will compare parent and child MDT, if child is remote, return -ENOTSUPP.

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.
