Subject[PATCH 4.14 25/27] ext4: track writeback errors using the generic tracking infrastructure
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Theodore Ts'o <tytso@mit.edu>

commit 95cb67138746451cc84cf8e516e14989746e93b0 upstream.

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().
