Thomas Schoebel-Theuer 87631d14fc all: make rmmod more robust when requests are flying 2013-01-23 20:06:50 +01:00
Thomas Schoebel-Theuer fdd3b251c0 all: replace kthread by brick_thread wrapper 2013-01-23 20:06:50 +01:00
Thomas Schoebel-Theuer c319230fa1 all: IO scheduling improvements, tuning 
Dastically boost random write performance on RAID controllers with BBUs.
Writeback is only performed when there is no IO contention / starvation.
The old IO contention controller was suited to workstations.
Now server loads are well-controlled even when BBUs are present.
