[PATCH 0/2] Locking issue in libiscsi and be2iscsi

2016-10-13 Thread Jitendra Bhivare 
These patches are being resent with required changes as per comments
for [PATCH 02/28] be2iscsi: Replace _bh with _irqsave/irqrestore

In IO handling path, there is no spin_lock taken with IRQs disabled
when calling into libiscsi, so no issues were found with use of
spin_lock_bh/spin_unlock_bh except for one in iscsi_eh_cmd_timeout.

This needs to be applied on top 11.2.0.0 of be2iscsi committed in
4.9/scsi-queue.

Jitendra Bhivare (2):
  libiscsi: Fix locking in __iscsi_conn_send_pdu
  be2iscsi: Replace _bh with _irqsave/irqrestore
