From aed7a6c476d90660ac5af860158407ae9fe61c68 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 26 Jun 2006 00:25:44 -0700 Subject: [PATCH] proc: Replace proc_inode.type with proc_inode.fd The sole renaming use of proc_inode.type is to discover the file descriptor number, so just store the file descriptor number and don't wory about processing this field. This removes any /proc limits on the maximum number of file descriptors, and clears the path to make the hard coded /proc inode numbers go away. Signed-off-by: Eric W.
