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" <tytso@mit.edu>
