It requires the snapshot code, which just recently made its way into the tree, and some new system calls to inform the filesystem that block X is actually free. However, this doesn't change the fact that fsck is not required in order to ensure correct operation after a crash. Depending on your access patterns, the block and inode leakage may be small enough to not matter. -GAWollman -- Garrett A.
