[PATCH] bcachefs: track writeback errors using the generic tracking infrastructure

[PATCH] bcachefs: track writeback errors using the generic tracking infrastructure

[Youling Tang]

From: Youling Tang <tangyouling@kylinos.cn>

We already using mapping_set_error() in bch2_writepage_io_done(), so all
we need to do is to use file_check_and_advance_wb_err() when handling
fsync() requests in bch2_fsync().
