From 2d36bfde8565b315e624302d12da5a7c9d195522 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 16 Apr 2010 16:22:45 -0400 Subject: NFS: Add helper functions for allocating filehandles and fattr structs NFS Filehandles and struct fattr are really too large to be allocated on the stack. This patch adds in a couple of helper functions to allocate them dynamically instead.
