From ce40fa78ef8f0e813392903c96de65b947298d16 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 29 Jan 2015 12:02:36 +0000 Subject: Cachefiles: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions Fix up the following scripted S_ISDIR/S_ISREG/S_ISLNK conversions (or lack thereof) in cachefiles: (1) Cachefiles mostly wants to use d_can_lookup() rather than d_is_dir() as it doesn't want to deal with automounts in its cache. (2) Coccinelle didn't find S_IS* expressions in ASSERT() statements in cachefiles.
