#     Merge tag 'errseq-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux
#     
#     Pull errseq infrastructure fix from Jeff Layton:
#      "The PostgreSQL developers recently had a spirited discussion about the
#       writeback error handling in Linux, and reached out to us about a
#       behavoir change to the code that bit them when the errseq_t changes
#       were merged.
#     
#       When we changed to using errseq_t for tracking writeback errors, we
#       lost the ability for an application to see a writeback error that
#       occurred before the open on which the fsync was issued. This was
#       problematic for PostgreSQL which offloads fsync calls to a completely
#       separate process from the DB writers.
#     
#       This patch restores that ability. If the errseq_t value in the inode
#       does not have the SEEN flag set, then we just return 0 for the sample.
#       That ensures that any recorded error is always delivered at least
#       once.
#     
#       Note that we might still lose the error if the inode gets evicted from
#       the cache before anything can reopen it, but that was the case before
#       errseq_t was merged. At LSF/MM we had some discussion about keeping
#       inodes with unreported writeback errors around in the cache for longer
#       (possibly indefinitely), but that's really a separate problem"
