[f2fs-dev] [PATCH 2/3] f2fs: run GCs synchronously given user requests

[Jaegeuk Kim]

When users set GC_URGENT or GC_MID, they expected to do GCs right away.
But, there's a condition to bypass it. Let's indicate we need to do now
in the thread.

.should_migrate_blocks is used to force migrating blocks in full
section, so what is the condition here? GC should not never select
a full section, right?

I think it'll move a full section given .victim_segno is not NULL_SEGNO,
as __get_victim will give a dirty segment all the time. wdyt?

However, in gc_thread_fun() victim_segno is NULL_SEGNO all the time.

I guess .should_migrate_blocks should only be set to true for
F2FS_IOC_FLUSH_DEVICE/F2FS_IOC_RESIZE_FS case? rather than GC_URGENT or GC_MID
case? See commit 7dede88659df ("f2fs: fix to allow migrating fully valid segment").

What do you mean? The gc_thread thread sets NULL_SEGNO, which prevents
from selecting the full section. But, f2fs_ioc_flush_device will set the
segno to move, and f2fs_resize_fs calls do_garbage_collect directly.

Yes, but I didn't get why this patch updates .should_migrate_blocks for
gc_thread_func() case? If this is added to avoid breaking from below condition,
I guess it's not necessary, since victim selected from gc_thread_func() will
always be dirty, so get_valid_blocks(sbi, segno, true) == BLKS_PER_SEC(sbi)
will be false anyway? or am I missing something?

		/*
		 * stop BG_GC if there is not enough free sections.
		 * Or, stop GC if the segment becomes fully valid caused by
		 * race condition along with SSR block allocation.
		 */
		if ((gc_type == BG_GC && has_not_enough_free_secs(sbi, 0, 0)) ||
			(!force_migrate && get_valid_blocks(sbi, segno, true) ==
							BLKS_PER_SEC(sbi)))
			return submitted;

Thanks,

I lost the previous test. :( IIRC, once I set GC_URGENT_HIGH, I've seen that
f2fs_gc couldn't migrate blocks quickly, even or never succeeded. And, I
also suspected the below condition tho, if I give force_migrate, it
simply worked. I just realized that that may be caused by large sections
having non-2MB-aligned zone capacity. Will check it again, as I found
some buggy flows in that case.

Let me drop this patch, since [1] series could fix the GC issue.
