This patch addresses an long standing race in iscsi_[rx,tx]_thread_pre_handler()
use of flush_signals(), and between iscsi_deallocate_extra_thread_sets() setting
ISCSI_THREAD_SET_DIE before calling kthread_stop().
It addresses the issue by both holding ts_state_lock before calling send_sig()
in iscsi_deallocate_extra_thread_sets(), as well as only calling flush_signals()
when ts->status != ISCSI_THREAD_SET_DIE within iscsi_[rx,tx]_thread_pre_handler()
code.
v2 changes:
- Add explicit complete(&ts->[rx,tx]_start_comp); before kthread_stop() in
iscsi_deallocate_extra_thread_sets()
- Drop left-over send_sig() calls in iscsi_deallocate_extra_thread_sets()
- Add kthread_should_stop() check in iscsi_signal_thread_pre_handler()
