- SCST_USER_UNREGISTER_DEVICE - to unregister device, flush mem reuse (SGV) cache and send UCMD_STATE_ON_CACHE_FREEING notifications for all freed buffers to the user space handler. Simple device close doesn't allow that, so all the cached buffers might look as "leaked" from the user space handler POV.
- SCST_USER_FLUSH_CACHE - to flush mem reuse (SGV) cache and send UCMD_STATE_ON_CACHE_FREEING notifications for all freed buffers to the user space handler
+ some cosmetics
Docs update is coming

- QLA_ISP targets in the main Makefile temporary disabled, since they don't support building with specified kernel version
git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@443 d57e44dd-8a1f-0410-8b47-8ef2f437770f
- Fixed 2 problems in scst_user on release() cleanup
- Added per-device memory limit and new scst.ko module parameter scst_max_dev_cmd_mem
- Cleanups, including important ones
- Version changed to 1.0.0-rc1

- PRIO queue was removed from scst_user. Instead, all priority commands now queued in the head of the regular queue. The corresponding code was removed from fileio_tgt as well. It necessary, in the future the priority queue can be easily restored from this patch.
- pre_unreg_sess() was removed from struct scst_dev_type. The corresponding code was removed from SCST core as well
- Almost all /proc/scsi_tgt commands now can fail after timeout (90 seconds) with EBUSY
- Fixed possible incorrect command's retry if double RESET UA is detected.
- Many minor changes and cleanups
Also docs were updated.

The patch below fixes the following class of checkpatch.pl errors:
ERROR("(foo*)" should be "(foo *)".
Or: another whitespace-only change.
I have verified that the output of svn diff -w -x is empty for this patch.

One of the Linux kernel patch submission requirements is that source files do
not contain trailing whitespace. The patch below removes trailing whitespace
from .c and .h source files.
Note: it might be more convenient to run the script I used to generate this
patch than to review and apply the patch below. This is how I generated and
verified the patch below:
cat <<EOF >./strip-trailing-whitespace
#!/bin/bash
trap "rm -f $t" EXIT
t=/tmp/temporary-file.$$
for f in "$@"
do
sed 's/[ ]*$//' <"$f" >"$t" && mv "$t" "$f"
done
EOF
chmod a+x ./strip-trailing-whitespace
find -name '*.[ch]' | xargs ./strip-trailing-whitespace
svn diff -x -w

- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
- Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
- Fixed possible dev_cmd_count underflow
- Minor iSCSI-SCST connection closing cleanups and fixes
- Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
- scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
- Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
- 64-bit cleanups
- Documented that iscsi-scst-adm is currently broken and explained why
- In user space Makefile's added possibility to specify external linker flags
- Minor performance optimizations
- Other minor cleanups

Particularly:
- Added ability for target drivers to set result of command's status delvery to initiator (see scst_set_delivery_status())
- Added ability for user space devices set some mode page parameters to make SCST core behave correspondingly
- TM improvements
- Few possible crashes fixed
- Logging improvements
- Performance improvements
- Docs updates
