From 5e2df28cc62fdc3f4900de23f4ec69e6312f78a4 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 6 Jun 2010 19:38:18 -0400 Subject: [PATCH] hostfs: pass pathname to init_inode() We will calculate it in all callers anyway, so there's no need to duplicate that inside. Moreover, that way we lose all failure exits in init_inode(), so it doesn't need to return anything.
