Hi,
what is the correct way of testing sequential cutoff?
I've:
- writeback mode
- sequential_cutoff to 1M
I'm doning:
dd if=/dev/zero of=/dev/bcache0 oflag=direct bs=16M count=200
After that dirty value is at 2.3G and bypassed is 29M.
I tested this with 3.17-rc4 and 3.10 kernel same results.
What's wrong here?
Thanks!
Greets,
Stefan
