5. Changelog since v5.0.0.2 (Open-iSCSI v 0.2)
===================================
* support non-immediate control plane commands
* flush queue in cnx_stop()
* fix queue add/remove
* Christoph Hellwig:
  - remove sys_iopl and <sys/io.h> (no need since oom_adj serves the 
purpose)
  - patch to use __be16/__be16 types for static typechecking with sparse 
-Wbitwise
  - make needlessly global symbols static
  - switch to proper goto-based error unwinding
  - kill zone_init cpp abuse
  - lots of 0 vs. NULL and one missing void in a prototype: cleanup
  - make two needlessly global symbols in iscsi_tcp.c static
  - use uintptr_t (the C99 type) to store a pointer instead of the 
locally defined ulong_t
* Mike Christie:
  - scsi_host_lookup: release scsi host handle right away
  - patch to move the scsi scanning to userspace.
  - request_bufflen: rely on the scsi_ml to set the correct value
  (INQUIRY, REQUEST_SENSE and REPORT_LUNS etc.)
* data_xmit(): cleanup, optimization
* MRDSL fix (discovered by Mike Christie)
* use GFP_ATOMIC in case of recovery and GFP_KERNEL in case of initial login
* race fix: max_r2t data_xmit() vs. r2t_rsp()
* release socket cleanup: done _after_ stopping data_xmit()
* padding: scsi_cmnd total length
* r2t sglist assertion fixes
* deprecate and remove control plane cnx/snx handles
* ERL=0 recovery fix for HeaderDigest=CRC32C
* iSCSI MIB and extended statistics: initial support, get_stats() API
* get_stats(): calculate actual size of statistics buffer
* integrate with scsi_transport_iscsi.[ch]
