From 8a8c74bf94fcdec058062d331b3d9777910778ab Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 26 Oct 2007 13:31:47 -0400 Subject: NFS: Ensure nfs_wcc_update_inode always converts file size to loff_t The nfs_wcc_update_inode() function omits logic to convert the type of the NFS on-the-wire value of a file's size (__u64) to the type of file size value stored in struct inode (loff_t, which is signed). Everywhere else in the NFS client I checked already correctly converts the file size type. This effects only very large files.
