Very Computer

Hello,

While compiling the clean 2.5.3-pre3 kernel I found the
drivers/md/raid5.c and drivers/md/multipatch.c could not get compiled.
Here is the compiling error for raid5.c:

......
-D__KERNEL__ -I/home/ming/views/253-pre3/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer
-fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2
-march=i686    -c -o raid5.o raid5.c
In file included from raid5.c:23:
/home/ming/views/253-pre3/include/linux/raid/raid5.h:218: parse error
before `md_wait_queue_head_t'
/home/ming/views/253-pre3/include/linux/raid/raid5.h:218: warning: no
semicolon
at end of struct or union
/home/ming/views/253-pre3/include/linux/raid/raid5.h:222: parse error
before `device_lock'
......

This failure also happened for 2.5.2 kernel.  Both of raid5.c and
multipatch.c use some data structures defined in md_compatible.h, which
was included in md.h before but does not exist under include/linux/raid
for now.  Could someone fix this?

Hello Evgeniy,

I omitted similar compile errors in the last email.  raid5.c and
multipath.c referenced a lot data structures defined in
md_compatible.h,  besides the two you added in your fix......

Thank you for your help.

As you mention md_compatible.h does not exist, it was introduced in 2.5.2
patch only in drivers/md/xor.c. But in at least pre5 all structures were
correctly defined in various md_{p,u,k}.h files. I've tried to find others
undefined symbols, but cann't. So i suggest you to upgrade a bit to pre6
or pre5 kernel ;), apply my litle patch and remove mention of
md_compatible.h in drivers/md/xor.c. And feel free to write all others
erorrs, if they will appear again.
