Subject: [PATCH] fs: convert a pile of fsync routines to errseq_t based reporting
From: Jeff Layton <jlayton@...hat.com>
This patch converts most of the in-kernel filesystems that do writeback
out of the pagecache to report errors using the errseq_t-based
infrastructure that was recently added. This allows them to report
errors once for each open file description.
Most filesystems have a fairly straightforward fsync operation. They
call filemap_write_and_wait_range to write back all of the data and
wait on it, and then (sometimes) sync out the metadata.
For those filesystems this is a straightforward conversion from calling
filemap_write_and_wait_range in their fsync operation to calling
file_write_and_wait_range.

Rolling up all of these conversions into a single patch, as Christoph
Hellwig suggested. Most of these are not tested, but the conversion
here is fairly straightforward.
Any maintainers who object, please let me know and I'll yank that
part out of this patch.
