• AddGrant, uses fs.propagate(ctx, np)
• RemoveGrant, PR in [owncloud] propagate mtime on RemoveGrant cs3org/reva#1115
• UpdateGrant, calls AddGrant
• CreateHome not necessary
• CreateDir, uses fs.propagate(ctx, np)
• CreateReference only in the share folder
• SetArbitraryMetadata, uses fs.propagate(ctx, np)
• UnsetArbitraryMetadata, uses fs.propagate(ctx, np)
• Delete, calls trash(), which uses fs.propagate(ctx, path.Dir(np))
• Move, uses fs.propagate(ctx, newName) and fs.propagate(ctx, path.Dir(oldName))
• RestoreRevision, uses fs.propagate(ctx, np)
• PurgeRecycleItem not necessary
• EmptyRecycle not necessary
• RestoreRecycleItem, uses fs.propagate(ctx, tgt)

Note that the owncloud storage driver does not support changing the storage on disk. It does not pick up changes on disk, which happen when the testsuite wipes a users home. The id mapping in redis needs to be wiped as well.
