Chris Mason 444528b3e6 Btrfs: always pin metadata in discard mode ... We have an optimization in btrfs to allow blocks to be immediately freed if they were allocated in this transaction and never written. Otherwise they are pinned and freed when the transaction commits. This isn't optimal for discard mode because immediately freeing them means immediately discarding them. It is better to give the block to the pinning code and letting the (slow) discard happen later. Signed-off-by: Chris Mason <chris.mason@oracle.com>		2009-10-14 10:32:50 -04:00
