From ea3983ace6b79c96e6ab3d3837e2eaf81ab881e2 Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Mon, 29 Apr 2013 16:21:11 -0700 Subject: fat: restructure export_operations Define two nfs export_operation structures,one for 'stale_rw' mounts and the other for 'nostale_ro'. The latter uses i_pos as a basis for encoding and decoding file handles. Also, assign i_pos to kstat->ino. The logic for rebuilding the inode is added in the subsequent patches.
