[PATCH v2 0/4] mm/gfs2: extend file_* API, and convert gfs2 to errseq_t error reporting

[Jeff Layton]

From: Jeff Layton <jlayton@xxxxxxxxxx>

I sent a small patch earlier this week to make sync_file_range use
errseq_t reporting.

This set respins that patch into a patch that adds a bit more file_*
infrastructure, and then patches to make sync_file_range and fsync
on gfs2 report writeback errors properly.

There's also a small cleanup patch for mm/filemap.c to consolidate
the DAX handling checks in the existing infrastructure.

Jeff Layton (4):
  mm: consolidate dax / non-dax checks for writeback
  mm: add file_fdatawait_range and file_write_and_wait
  fs: convert sync_file_range to use errseq_t based error-tracking
  gfs2: convert to errseq_t based writeback error reporting for fsync
