automatic writes..

[Paramasivam Kartik]

Hi everybody,

this is a question about the linux source code.

i want to test my modified raid code for reads only.
Once after every couple of read requests, 
a write request is automatically generated, i.e.
'fsync_dev' is called which calls 'sync_buffers'.

i want to modify the interval after which it
does the BUF SYNC.

it looks like i have to change some #defined value.
Could anyone tell me which/where this value is.
 
Thankyou in advance.

Regards,
