Subject: [GIT PULL] target updates for v3.8-rc1
Hello Linus!
Here are the target updates for v3.8-rc1 merge window code. Please go
ahead and pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next
Just a heads up that there is a minor merge conflict that you'll
encounter in target_handle_task_attr() code, that sfr has been carrying
a fix for recently within -next. After dropping the HEAD section, the
resolution should look like:
http://git.kernel.org/?p=linux/kernel/git/nab/target-pending.git;a=commitdiff;h=50f966ab0a8630cacb46bb382cd2822a5c1448ac
It has been a very busy development cycle this time around in target
land, with the highlights including:
- Kill struct se_subsystem_dev, in favor of direct se_device usage (hch)
- Simplify reservations code by combining SPC-3 + SCSI-2 support
for virtual backends only (hch)
- Simplify ALUA code for virtual only backends, and remove left
over abstractions (hch)
- Pass sense_reason_t as return value for I/O submission path (hch)
- Refactor MODE_SENSE emulation to allow for easier addition of
new mode pages. (roland)
- Add emulation of MODE_SELECT (roland)
- Fix bug in handling of ExpStatSN wrap-around (steve)
- Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve)
- Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab)
- Convert ib_srpt to use modern target_submit_cmd caller +
drop legacy ioctx->kref usage (nab)
- Convert ib_srpt to use modern target_submit_tmr caller (nab)
- Add link_magic for fabric allow_link destination target_items
for symlinks within target_core_fabric_configfs.c code (nab)
- Allocate pointers in instead of full structs for
config_group->default_groups (sebastian)
- Fix 32-bit highmem breakage for FILEIO (sebastian)
All told, hch was able to shave off another ~1K LOC by killing the
se_subsystem_dev abstraction, along with a number of PR + ALUA
simplifications. Also, a nice patch by Roland is the refactoring of
MODE_SENSE handling, along with the addition of initial MODE_SELECT
emulation support for virtual backends.
Sebastian found a long-standing issue wrt to allocation of full
config_group instead of pointers for config_group->default_group[]
setup in a number of areas, which ends up saving memory with big
configurations. He also managed to fix another long-standing BUG wrt to
broken 32-bit highmem support within the FILEIO backend driver.
Thank you again to everyone who contributed this round!
