6.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chunhai Guo <guochunhai@xxxxxxxx>

[ Upstream commit 2bd4df8fcbc72f58ce3c62ed021ab291ca42de0b ]

Now f2fs support four block allocation modes: lfs, adaptive,
fragment:segment, fragment:block. Only lfs mode is allowed with zoned block
device feature.

Fixes: 6691d940b0e0 ("f2fs: introduce fragment allocation mode mount option")
