Vladislav Bolkhovitin 9c10f10b00 Experimental optimization. Suppose that if sock_recvmsg() returned less data than requested, then next time it will return -EAGAIN, so there's no point to call it again.

Vladislav Bolkhovitin 82b04b2a00 Merge of the sysfs branch. To enable the sysfs interface you should run "make disable_proc". To switch back on the procfs interface you should run "make disable_proc". 
The sysfs intarface is mostly finished. Only initiators-oriented access control not implemented and not all target drivers are updated. Only qla2x00t has been fully updated.

Vladislav Bolkhovitin cc83f517ea - Fix for a possible DoS, when misbehavine scst_user's handler hangs several memory allocations (= count of iSCSI read threads) and by so prevents other sessions from being served correctly. Spotted by Erez Zilber <erezzi.list@gmail.com> 
- iSCSI read state machine cleanups

 - Fix a race when just freed iSCSI session accessed, because the corresponding SCST session is still being unregistered.

Vladislav Bolkhovitin 7bdc38faf2 The most recent version of the sparse static source code checking tool does 
now report functions that are called with a lock held but that are missing
__acquires() and __releases() annotations. The patch below adds such
annotations and makes the following sparse warnings disappear:

drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock
drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock
drivers/scst/scst_local/scst_local.c:554:30: warning: context imbalance in 'scst_local_queuecommand' - unexpected unlock

The patch below has been tested by comparing the output of
"scripts/run-regression-tests 2.6.30.3" before and after the patch was applied.

Vladislav Bolkhovitin 102603f46d We can't mark sess as shutting down in close_conn(), because at that time it might have pending commands. Otherwise, in case of reinstatement it might lead to data corruption, because commands in being reinstated session can be executed after commands in the new session.
