nfs: Replace kmap() with kmap_local_page()
The use of kmap() is being deprecated in favor of kmap_local_page(). With kmap_local_page(), the mapping is per thread, CPU local and not globally visible. Furthermore, the mapping can be acquired from any context (including interrupts). Therefore, use kmap_local_page() in nfs_do_filldir() because this mapping is per thread, CPU local, and not globally visible. Suggested-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Fabio M.
