Hello,

these two patches fix a long standing issue that long running fstrim request
can block a system suspend as reported by Len Brown in [1]. The solution is
quite simple - just report whatever we have trimmed upto now since discard
is an advisory call anyway. What makes things a bit more complex is handling
of group's TRIMMED bit - we deal with that in patch 1.
