内核编译出错，请大家帮帮忙!!

red_eyed_hare

我装的是red hat 9.0，2.4.20-8的内核，现在我想把/dev file system support 编译选项编译进内核，我选择后编译出现以下问题
make bzImage后：
gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-8/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686   -nostdinc -iwithprefix include -DKBUILD_BASENAME=base  -DEXPORT_SYMTAB -c base.c
base.c: In function `is_devfsd_or_child':
base.c:1417: structure has no member named `p_opptr'
base.c:1417: structure has no member named `p_opptr'
make[3]: *** [base.o] Error 1
make[3]: Leaving directory `/usr/src/linux-2.4.20-8/fs/devfs'
make[2]: *** [first_rule] Error 2
make[2]: Leaving directory `/usr/src/linux-2.4.20-8/fs/devfs'
make[1]: *** [_subdir_devfs] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.20-8/fs'
make: *** [_dir_fs] Error 2
网上有很多这样的问题，但是没人解，但我觉得一定有人做过
请有经验的大侠帮我看看吧，非常感谢！

看样子这是一个redhat的bug，
看看这个帖子：
http://oss.sgi.com/archives/xfs/2003-10/msg00795.html

#if LINUX_VERSION_CODE < KERNEL_VERSION(2,5,1)
-    for (p = current->p_opptr; p != &init_task; p = p->p_opptr)
+    for (p = current->real_parent; p != &init_task; p = p->real_parent)

好像2.5.1的内核要把p_opptr 改成real_parent
