Comment 4 for bug 1770003

Hi Joseph,

The original patchset just included 4 patches, they are:

d8630bb scsi: qla2xxx: Serialize session deletion by using work_lock
1ae634e scsi: qla2xxx: Serialize session free in qlt_free_session_done
9cd883f scsi: qla2xxx: Fix session cleanup for N2N
eaf75d1 scsi: qla2xxx: Fix double free bug after firmware timeout

The other three patches came as a requirement to backport these 4 patches.

On top of it, the commit id d8630bb95f46 had a regression which would require the last patch:

1c6cacf scsi: qla2xxx: Fixup locking for session deletion
