Subject: Turn off readahead completely
Date: Thu, 21 Oct 2021 13:16:46 +0000	[thread overview]
Message-ID: <8aa213d5d5464236b7e47aaa6bb93bb8@dlr.de> (raw)

Hello everyone,

I need to turn readahead off completely in order to do my experiments. 
Is there any way to turn it off completely?

Setting /sys/block/<dev>/queue/read_ahead_kb to 0 causes readahead to become 4kb.

Thanks,
Azat
