Subject: [PATCH v3 2/3] f2fs: check PageWriteback flag for ordered case
For all ordered cases in f2fs_wait_on_page_writeback(), we need to
check PageWriteback status, so let's clean up to relocate the check
into f2fs_wait_on_page_writeback().
Signed-off-by: Chao Yu <yuchao0@...wei.com>
---
v3:
- add parameter to skip check for unlocked page.
