From: Pavel Tikhomirov <ptikhomi...@virtuozzo.com>
Add tracking of writeback errors using file_check_and_advance_wb_err()
for each file. This ensures proper error reporting and aligns with
modern error handling practices.
Similar to upstream commit:
95cb67138746 ("ext4: track writeback errors using the generic tracking
infrastructure")
Part of rework for ext4_sync_files function.
Fixes: 26337aacaafa9 ("ext4: add mfsync support")
https://virtuozzo.atlassian.net/browse/VSTOR-107255
