From 7669e8fb09da47dd45c07a51394f01031ea81da8 Mon Sep 17 00:00:00 2001 From: "Steven J. Magnani" Date: Thu, 4 Oct 2012 17:14:45 -0700 Subject: fat (exportfs): fix dentry reconnection Maintain an index of directory inodes by starting cluster, so that fat_get_parent() can return the proper cached inode rather than inventing one that cannot be traced back to the filesystem root. Add a new msdos/vfat binary mount option "nfs" so that FAT filesystems that are _not_ exported via NFS are not saddled with maintenance of an index they will never use. Finally, simplify NFS file handle generation and lookups. An ext2-congruent implementation is adequate for FAT needs. Signed-off-by: Steven J.
