iget: stop PROCFS from using iget() and read_inode()
has been removed from the -mm tree. Its filename was
iget-stop-procfs-from-using-iget-and-read_inode.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: iget: stop PROCFS from using iget() and read_inode()
From: David Howells <[EMAIL PROTECTED]>
Stop the PROCFS filesystem from using iget() and read_inode(). Merge
procfs_read_inode() into procfs_get_inode(), and have that call iget_locked()
instead of iget().
