## Description

In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix fsck inconsistency caused by FGGC of node block  During FGGC node block migration, fsck may incorrectly treat the migrated node block as fsync-written data.  The reproduction scenario: root@vm:/mnt/f2fs# seq 1 2048 | xargs -n 1 ./test_sync // write inline inode and sync root@vm:/mnt/f2fs# rm -f 1 root@vm:/mnt/f2fs# sync root@vm:/mnt/f2fs# f2fs_io gc_range // move data block in sync mode and not write CP   SPO, "fsck --dry-run" find inode has already checkpointed but still   with DENT_BIT_SHIFT set  The root cause is that GC does not clear the dentry mark and fsync mark during node block migration, leading fsck to misinterpret them as user-issued fsync writes.  In BGGC mode, node block migration is handled by f2fs_sync_node_pages(), which guarantees the dentry and fsync marks are cleared before writing.  This patch move the set/clear of the fsync|dentry marks into __write_node_folio to make the logic clearer, and ensures the fsync|dentry mark is cleared in FGGC.
