Subject: [PATCH] ext4: track writeback errors using the generic tracking
infrastructure
Git-commit: 95cb67138746451cc84cf8e516e14989746e93b0
Patch-mainline: v5.0-rc1
References: bsc#1124982
We already using mapping_set_error() in fs/ext4/page_io.c, so all we
need to do is to use file_check_and_advance_wb_err() when handling
fsync() requests in ext4_sync_file().
