Subject: bcachefs: track writeback errors using the generic tracking infrastructure
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=8b0882505d012ef5f309a1b547fae53080a62f07;p=users%2Fjedix%2Flinux-maple.git

bcachefs: track writeback errors using the generic tracking infrastructure

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().
