Chris Mason 451d7585a8 Btrfs: add mount -o ssd_spread to spread allocations out ... Some SSDs perform best when reusing block numbers often, while others perform much better when clustering strictly allocates big chunks of unused space. The default mount -o ssd will find rough groupings of blocks where there are a bunch of free blocks that might have some allocated blocks mixed in. mount -o ssd_spread will make sure there are no allocated blocks mixed in. It should perform better on lower end SSDs. Signed-off-by: Chris Mason <chris.mason@oracle.com>		2009-06-10 11:29:52 -04:00
