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
