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. Honza [1] https://bugzilla.kernel.org/show_bug.cgi?id=216322
