2025-07-28f2fs: directly add newly allocated pre-dirty nat entry to dirty set listwangzijie
When we need to alloc nat entry and set it dirty, we can directly add it to dirty set list(or initialize its list_head for new_ne) instead of adding it to clean list and make a move. Introduce init_dirty flag to do it. Signed-off-by: wangzijie <wangzijie1@honor.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2025-07-28f2fs: avoid redundant clean nat entry move in lru listwangzijie
__lookup_nat_cache follows LRU manner to move clean nat entry, when nat entries are going to be dirty, no need to move them to tail of lru list. Introduce a parameter 'for_dirty' to avoid it.

To fix this issue, let's add sanity check for node id of all direct nodes during f2fs_get_dnode_of_data().

Although, it tags SBI_NEED_FSCK, checkpoint can not persist it due to deadloop. Let's call f2fs_handle_error(, ERROR_INCONSISTENT_NAT) to record such error into superblock, it expects fsck can detect the error and repair inconsistent nat.blkaddr after device reboot. Note that, let's add sanity check in f2fs_get_node_info() to detect in-memory nat.blkaddr inconsistency, but only if CONFIG_F2FS_CHECK_FS is enabled.
