Greetings all,
It is my honor to announce that TCM/LIO v4.0.0-rc5 for v2.6.36-rc8 has
been tagged and pushed into lio-core-2.6.git/lio-4.0 on kernel.org. It
has been almost exactly one month since v4.0.0-rc4 was released, and
development has continued to be quite busy as some of the new v4.0
emulation features are been shaken out on linux-scsi. This released
includes the following major items:
*) Add proper TCM/pSCSI BIDI-COMMAND passthrough (Boaz Harrosh assist)
*) Allow MappedLUNs with non existent struct se_lun, which allowed
us to drop the struct config_group_operations->check_link() call
alltogether (Joel Becker assist)
*) Add UNMAP and Block Limits VPD page support (Martin Petersen assist)
*) Add Thin Provisioning VPD page emulation (Martin Petersen assist)
*) Add proper extended CDB support with by default 32-bit CDBs.
(Martin Petersen and Boaz Harrosh assist)
*) Add WRITE_SAME_16 and WRITE_SAME_32 w/ UNMAP-1 support (Martin Petersen assist)
*) Add target_fabric_tf_ops_check() sanity checks at TCM fabric module
registration time
*) Unify TCM subsysystem CDB emulation for INQUIRY, READ_CAPACITY*, UNMAP,
WRITE_SAME_* and SYNCHRONIZE_CACHE (Christoph Hellwig assist)
*) Add struct se_dev_limits for subsystem ->create_virtdevice()
(Christoph Hellwig assist)
At this point I will be accepting bugfixes and other cleanups recommened
by community members to v4.0 for .37 mainline in the next two weeks, and
will be pushing new features bits into v4.1 for .38 as the remaining .37
items are resolved.
Once again, a big thanks go out to the community members involved in
this release. Thank you!
