From 0b3fca1fd1499f0f5a7486d494f96538f2b7e5b9 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 15 Jun 2013 11:37:47 +0400 Subject: [PATCH] kill find_inode_number() the only remaining caller (in ncpfs) is guaranteed to return 0 - we only hit it if we'd just checked that there's no dentry with such name.
