cheat sheet:

If ->i_lock is held, then:

state = inode->i_state => state = inode_state_read(inode)
inode->i_state |= (I_A | I_B) => inode_state_set(inode, I_A | I_B)
inode->i_state &= ~(I_A | I_B) => inode_state_clear(inode, I_A | I_B)
inode->i_state = I_A | I_B => inode_state_assign(inode, I_A | I_B)

If ->i_lock is not held or only held conditionally:

state = inode->i_state => state = inode_state_read_once(inode)
inode->i_state |= (I_A | I_B) => inode_state_set_raw(inode, I_A | I_B)
inode->i_state &= ~(I_A | I_B) => inode_state_clear_raw(inode, I_A | I_B)
inode->i_state = I_A | I_B => inode_state_assign_raw(inode, I_A | I_B)
