nilfs2: another dat for garbage collection
NILFS2 uses another DAT inode during garbage collection to ensure atomicity and consistency of the DAT in the transient state. This twin inode is called GCDAT. This adds functions to initialize the GCDAT and to switch page caches and B-tree node caches between these two inodes.
