Re: [f2fs-dev] [PATCH v3 03/17] f2fs: support regular file buffered writes on large folios

[Nanzhe Zhao]

Hi Chao,

Thanks for review!

You mean after I take Daeho's suggestion:

> Maybe f2fs_folio_may_unlock_balance_fs() could call
> f2fs_folio_wait_writeback() after relocking?

we can have a chance to relocate
prepare_large_folio_write_begin()/prepare_large_folio_atomic_write_begin()
after

> else if (!folio_test_large(folio))
>	err = prepare_write_begin(sbi, folio, pos, blen,
>					&blkaddr, &need_balance);
> else
>	err = prepare_large_folio_write_begin(...);

before original f2fs_write_begin's f2fs_folio_wait_writeback, right?
