Subject: query, which io scheduler is active?
Date: Thu, 26 May 2005 03:38:55 +0200 [thread overview]
Message-ID: <015201c56193$ae5f86f0$2000000a@schlepptopp> (raw)
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
