staging: add Lustre file system client support Lustre is the most deployed distributed file system in the HPC (High Performance Computing) world. The patch adds its client side support. The code is not very clean and needs to live in drivers/staging for some time for continuing cleanup work. See drivers/staging/lustre/TODO for details. The code is based on Lustre master commit faefbfc04 commit faefbfc0460bc00f2ee4c1c1c86aa1e39b9eea49 Author: Alex Zhuravlev <alexey.zhuravlev@intel.com> Date: Tue Apr 30 23:05:21 2013 +0400 LU-3244 utils: tunefs.lustre should preserve virgin label Plus a few under-review patches on Whamcloud gerrit: 3.8 kernel support: http://review.whamcloud.com/#change,5973 http://review.whamcloud.com/#change,5974 http://review.whamcloud.com/#change,5768 http://review.whamcloud.com/#change,5781 http://review.whamcloud.com/#change,5763 http://review.whamcloud.com/#change,5613 http://review.whamcloud.com/#change,5655 3.9 kernel support: http://review.whamcloud.com/#change,5898 http://review.whamcloud.com/#change,5899 Kconfig/Kbuild: http://review.whamcloud.com/#change,4646 http://review.whamcloud.com/#change,4644 libcfs cleanup: http://review.whamcloud.com/#change,2831 http://review.whamcloud.com/#change,4775 http://review.whamcloud.com/#change,4776 http://review.whamcloud.com/#change,4777 http://review.whamcloud.com/#change,4778 http://review.whamcloud.com/#change,4779 http://review.whamcloud.com/#change,4780 All starting/trailing whitespaces are removed, to match kernel coding style.
