cheat sheet:
Suppose flags I_A and I_B are to be handled, then if ->i_lock is held:

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

If ->i_lock is not held or only held conditionally, add "_once"
suffix for the read routine or "_raw" for the rest:

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