6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chao Yu <chao@xxxxxxxxxx>
[ Upstream commit 7461f37094180200cb2f98e60ef99a0cea97beec ]
f2fs doesn't support different blksize in one instance, so
bytes_to_blks() and blks_to_bytes() are equal to F2FS_BYTES_TO_BLK
and F2FS_BLK_TO_BYTES, let's use F2FS_BYTES_TO_BLK/F2FS_BLK_TO_BYTES
instead for cleanup.
