Does anyone know why in the out_of_memory(int gfp_mask) function has
the following conditions:
* If it's been a long time since last failure,
* we're not oom.
*/
if (since > 5*HZ)
goto reset;
/*
* If we haven't tried for at least one second,
* we're not really oom.
*/
since = now - first;
if (since < HZ)
goto out_unlock;
/*
* If we have gotten only a few failures,
* we're not really oom.
*/
if (++count < 10)
goto out_unlock;
These conditions prevent the oom_kill() function to be invoked. Could
anyone explain about it?
Why 5 seconds, count variable less than 10 ...?
BR,
Mauricio Lin.
