From 229f0917123219ac40fbea81f837af37ea378802 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 2 Feb 2015 00:37:01 -0500 Subject: vfs: add find_inode_nowait() function Add a new function find_inode_nowait() which is an even more general version of ilookup5_nowait(). It is designed for callers which need very fine grained control over when the function is allowed to block or increment the inode's reference count.
