[PATCH -next 0/2] nfs: check writeback errors correctly

[ChenXiaoSong <chenxiaosong2@huawei.com>]

This series fixes nfs writeback error checking bugs.

If there is an error during the writeback process, it should be returned
when user space calls close() or fsync().

filemap_sample_wb_err() will return 0 if nobody has seen the error yet,
then filemap_check_wb_err() will return the unchanged writeback error.

ChenXiaoSong (2):
  nfs: nfs{,4}_file_flush should consume writeback error
  nfs: nfs_file_write() check writeback errors correctly
