Subject: Re: [PATCH] mm/memcg: reorder retry checks for clarity in try_charge_memcg
From: Dipendra Khadka <kdipendra88@...il.com>
Hi Shakeel,
This response is not generated by AI.
I have applied following changes in try_charge_memcg() and
please find the respective logs below which shows that after
sigkill, its doing unnecessary full reclaim attempts.
On rest, I agree with you.Hence, I think this patch makes
sense.
Change:
if (mem_cgroup_margin(mem_over_limit) >= nr_pages)
{
pr_info("Dipendra MEMCG_RECLAIM: Reclaim successful, reclaimed
%lu pages\n",
nr_reclaimed);
goto retry;
}
pr_info("Dipendra MEMCG_RECLAIM: Reclaimed %lu pages but still
insufficient\n", nr_reclaimed);
if (!drained) {
drain_all_stock(mem_over_limit);
drained = true;
goto retry;
}
if (gfp_mask & __GFP_NORETRY)
goto nomem;
pr_info("Dipendra MEMCG_RECLAIM: Memory limit exceeded, attempting
reclaim\n");
pr_info("Dipendra MEMCG_RECLAIM: Target=%lu pages, memcg=%s\n",
nr_pages, memcg->css.cgroup->kn->name);
/*
* Even though the limit is exceeded at this point, reclaim
* may have been able to free some pages. Retry the charge
* before killing the task.
*
* Only for regular pages, though: huge pages are rather
* unlikely to succeed so close to the limit, and we fall back
* to regular pages anyway in case of failure.
*/
if (nr_reclaimed && nr_pages <= (1 << PAGE_ALLOC_COSTLY_ORDER))
goto retry;
if (passed_oom && task_is_dying()) {
pr_info("Dipendra MEMCG: retry while dying!\n");
pr_info(" pid=%d comm=%s nr_retries=%d gfp=0x%x\n",
current->pid, current->comm, nr_retries, gfp_mask);
dump_stack();
}
if (nr_retries--)
{
pr_info("Dipendra: nr_retires =%d\n",nr_retries);
goto retry;
}
if (gfp_mask & __GFP_RETRY_MAYFAIL)
goto nomem;
/* Avoid endless loop for tasks bypassed by the oom killer */
if (passed_oom && task_is_dying())
{
pr_info("Dipendra : I am dying already.....\n");
goto nomem;
}
/*
* keep retrying as long as the memcg oom killer is able to make
* a forward progress or bypass the charge if the oom killer
* couldn't make any progress.
*/
pr_info("Dipendra %s:%d:%s(): calling mem_cgroup_oom\n", __FILE__,
__LINE__, __func__);
if (mem_cgroup_oom(mem_over_limit, gfp_mask,
