Hello,

dmesg tells:

---snip---
Kernel command line: root=/dev/sda2 
---snip---
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered
---snip---

ok - there are 4 types of io schedulers - but - how can one see/query, which i/o scheduler is the currently "active" one?

It seems that SuSE Kernel shows this via

if (!printed) {
                printed = 1;
                printk("Using %s io scheduler\n", chosen_elevator->elevator_name);
        }

in drivers/block/ll_rw_blk.c

I can supply a patch if you like.

regards
roland
