From 3661d28615ea580c1db02a972fd4d3898df1cb01 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 14 Sep 2009 22:59:50 -0400 Subject: [PATCH] ext4: Fix include/trace/events/ext4.h to work with Systemtap Using relative pathnames in #include statements interacts badly with SystemTap, since the fs/ext4/*.h header files are not packaged up as part of a distribution kernel's header files. Since systemtap doesn't use TP_fast_assign(), we can use a blind structure definition and then make sure the needed header files are defined before the ext4 source files #include the trace/events/ext4.h header file. https://bugzilla.redhat.com/show_bug.cgi?id=512478 Signed-off-by: "Theodore Ts'o" --- fs/ext4/super.c | 1 + include/trace/events/ext4.h | 6 ++++-- 2 files changed, 5 insertions(+), 2 deletions(-) diff --git a/fs/ext4/super.c b/fs/ext4/super.c index 04c693357336..af95dd8ba54b 100644 --- a/fs/ext4/super.c +++ b/fs/ext4/super.c @@ -45,6 +45,7 @@ #include "ext4_jbd2.h" #include "xattr.h" #include "acl.h" +#include "mballoc.h" #define CREATE_TRACE_POINTS #include diff --git a/include/trace/events/ext4.h b/include/trace/events/ext4.h index 68b53c7ef8a7..6fe6ce9ee071 100644 --- a/include/trace/events/ext4.h +++ b/include/trace/events/ext4.h @@ -5,10 +5,12 @@ #define _TRACE_EXT4_H #include -#include "../../../fs/ext4/ext4.h" -#include "../../../fs/ext4/mballoc.h" #include +struct ext4_allocation_context; +struct ext4_allocation_request; +struct ext4_prealloc_space; + TRACE_EVENT(ext4_free_inode, TP_PROTO(struct inode *inode), -- 2.39.5
