6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yongpeng Yang <yangyongpeng1@xxxxxxxx>
[ Upstream commit 43563069e1c1df417d2eed6eca8a22fc6b04691d ]
In the __f2fs_init_atgc_curseg->get_atssr_segment calling,
curseg->segno is NULL_SEGNO, indicating that there is no summary
block that needs to be written.
Fixes: 093749e296e2 ("f2fs: support age threshold based garbage collection")
