To create dirty blocks in memory each block type caller currently gets a reference on a created block and then dirties it. The reference it gets could be an existing cached block that stale readers are currently using. This creates a problem with our block consistency protocol where writers can dirty and modify cached blocks that readers are currently reading in memory, leading to read corruption. This commit is the first step in addressing that problem. We add a scoutfs_block_dirty_ref() call which returns a reference to a dirtied block from the block core in one call. We're only changing the callers in this patch but we'll be reworking the dirtying mechanism in an upcoming patch to avoid corrupting readers. Signed-off-by: Zach Brown <zab@versity.com>
