Hello everyone,
Just a quick note that I've updated the newformat2 kernel branch to
include some fixes for buffered IO stalls and a new mount -o ssd_spread
mount option that should perform better than regular mount -o ssd when
used on lower end SSDs.
The big difference is that mount -o ssd_spread forces allocations to
find fully free areas, where mount -o ssd will find rough groupings of
free blocks that might have allocated blocks mixed in.
Tomorrow I'll add some autodetection for devices that have the
non-rotational flag set, which is a hint the block layer gives us that
we're operating on an SSD.
-chris
