Subject: [ANNOUNCE] TCM/LIO v4.0.0-rc3 for 2.6.36-rc3
Newsgroups: gmane.linux.kernel
Date: Monday 30th August 2010 00:18:27 UTC (over 6 years ago)
Greetings all,

I am very pleased to announce that TCM/LIO v4.0.0-rc3 for the 2.6.36-rc3
kernel
has been pushed into lio-core-2.6.git/lio-4.0.  Along with the numerous
bugfixes
listed in the shortlog below, the main cleanups and features since
v4.0.0-rc2
was released earlier this month include:

	*) Major cleanups of TCM/pSCSI struct scsi_device registration code (hch
assist)
	*) Remove legacy linux_blockdevice_[claim,release]() usage (hch assist)
	*) Fix struct se_mem memory mapping across N struct se_task for
	   max_sectors=255 backstores
	*) Conversion of TCM Core to follow mainline convention and use
	   include/linux/scatterlist.h wrappers wherever possible.
	*) Add proper 4k -> 512 block_size conversion for TCM/IBLOCK (jaxboe
assist)
	*) New tcm_mod_builder.py script and mini-HOWTO for generating new
	   TCM fabric modules with functional+runnable configfs skeletons
	*) TCM level SYNCHRONIZE_CACHE_* emulation w/ support for WriteCache and
	   FUA WRITE emulation with FILEIO and IBLOCK subsystem plugins. (hch
assist)
	   
A big thanks (again) to hch, jaxboe, and everyone involved in this release
for their very gracious help and feedback!

Best,

--nab
