Hi there,

my kernel stops compiling with this:

gcc -D__KERNEL__ -I/usr/src/linux-2.4.10-pre6/include -Wall -Wstrict-prototypes 
-Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -
mpreferred-stack-boundary=2 -march=i686    -c -o rd.o rd.c
rd.c: In function `rd_ioctl':
rd.c:262: invalid type argument of `->'
make[3]: *** [rd.o] Error 1
make[3]: Leaving directory `/usr/src/linux-2.4.10-pre6/drivers/block'
make[2]: *** [first_rule] Error 2
make[2]: Leaving directory `/usr/src/linux-2.4.10-pre6/drivers/block'
make[1]: *** [_subdir_block] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.10-pre6/drivers'
make: *** [_dir_drivers] Error 2

I checked the patch (patch-2.4.10-pre6) and thought maybe there is 
a "&" missing, where someone changed &inode->... to rd_bdev[... ?
Anyways, i changed it and it seems to compile ;)
