From a7a76cefc4b12bb6508afa4c77f11c2752cc365d Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 18 Apr 2005 21:57:33 -0700 Subject: [PATCH] [PATCH] debugfs: Reduce dependencies The current include file is a little fragile in that it is not self-contained and hence may cause compile warnings or errors depending on the files included before it, the kernel config and the architecture. This patch makes things a little more robust by: - including to get definitions of u32, mode_t, and so on. - forward declaring struct file_operations. - including when CONFIG_DEBUG_FS is not set The last change is particularly useful, as a kernel developer is likely to build with debugfs always enabled and never see the build breakage cased if debugfs is disabled.
