OUPS 2.5.69-bk19 coda-inode.c/slab.c

following BUG() is started when coda is included into kernel. I have not tried module, but i bet it will couse the same error.

coda_init_inodecache runs kmem_cache_create which couses oups. Removing following lines from slab.c renders system stable. But this is not a cure. As i am not using coda it self, i really don't know if it is running stable.

slab.c snip:

        /*
         * Always checks flags, a caller might be expecting debug
         * support which isn't available.
         */
         /*
        if (flags & ~CREATE_MASK){
                        printk("dupa2\n");
                        _BUG();
                BUG();
        }

this is in kmem_cache_create fn.

Although I don't run the -bkXX releases, as far as I can see this is not related to anything in Coda bug, but probably a missing change to slab.c.

A flag was added to the slabcache to identify reclaimable slabs. I can see how this BUG would get triggered if your kernel was linked with an old version of slab.o or is missing the SLAB_RECLAIM_ACCOUNT related changes in slab.c.

Maybe "make clean ; make bzImage modules" will fix it?

I am allways doing that in case of problems. So this is not a case, I bet this is missing patch for slab.c. Becouse this part i showed (along with mine two debug lines) does not look to good.
