From: Eric Biggers <[email protected]> As was done for generic_update_time(), only pass I_DIRTY_TIME to __mark_inode_dirty() when the inode's timestamps were actually updated and lazytime is enabled. This avoids a weird edge case where I_DIRTY_TIME could be set in i_state when lazytime isn't enabled.
