From 5ca29607331fe37980dc3b488793ef8b1409b722 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 17 Jul 2007 04:04:29 -0700 Subject: knfsd: exportfs: remove iget abuse When the exportfs interface was added the expectation was that filesystems provide an operation to convert from a file handle to an inode/dentry, but it kept a backwards compat option that still calls into iget. Calling into iget from non-filesystem code is very bad, because it gives too little information to filesystem, and simply crashes if the filesystem doesn't implement the ->read_inode routine. Fortunately there are only two filesystems left using this fallback: efs and jfs. This patch moves a copy of export_iget to each of those to implement the get_dentry method. While this is a temporary increase of lines of code in the kernel it allows for a much cleaner interface and important code restructuring in later patches.
