Dear maintainers,
A f2fs patch should be backported from upstream mainline to the stable
5.15.y branches. The patch's information is shown as below:
[Subject]
f2fs: fix UAF issue in f2fs_merge_page_bio()
[Upstream commit ID]
edf7e9040fc52c922db947f9c6c36f07377c52ea
[Kernel version]
5.15.y
[Why]
We encountered the same issue on the 5.15 kernel version. After
referring to the modifications in the upstream, the issue was solved.
Thanks,
Jiucheng

Great, please provide a working backport that you have tested for this
branch, and all of the newer stable branches, and we will be glad to
apply it. As-is, it does not apply at all.
thanks,
