Hi Matthew,

After merging the ida tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/target/iscsi/iscsi_target_login.c: In function 'iscsi_login_zero_tsih_s1':
drivers/target/iscsi/iscsi_target_login.c:376:16: error: 'sess_idr_lock' undeclared (first use in this function); did you mean 'auth_id_lock'?
  spin_lock_bh(&sess_idr_lock);
                ^~~~~~~~~~~~~
                auth_id_lock
drivers/target/iscsi/iscsi_target_login.c:376:16: note: each undeclared identifier is reported only once for each function it appears in
drivers/target/iscsi/iscsi_target_login.c:377:14: error: 'sess_idr' undeclared (first use in this function); did you mean 'sess_ida'?
  idr_remove(&sess_idr, sess->session_index);
              ^~~~~~~~
              sess_ida

Caused by commit

  9cd88edeaa9d ("target/iscsi: Allocate session IDs from an IDA")

interacting with commit

  ad86353cbddb ("iscsi target: fix session creation failure handling")

I have reverted commit 9cd88edeaa9d for today.
