Well, in addition to my last mail the following patch isn't a fix, but it might point to the culprit. If I apply this patch against latest tree, then the crash doesn't occur :
diff --git a/include/linux/statfs.h b/include/linux/statfs.h index 0166d32..e336e70 100644 --- a/include/linux/statfs.h +++ b/include/linux/statfs.h @@ -15,8 +15,8 @@ struct kstatfs { __kernel_fsid_t f_fsid; long f_namelen; long f_frsize; - long f_flags; long f_spare[4]; + long f_flags; };
