The 1st patch improves fetch command removal and canceling, which is
reported as risk from AI.

The 2nd patch adds UBLK_F_NO_AUTO_PART_SCAN for disabling partition
scanning during adding disk.

The other patches improves ublk selftests:
	- rename test_generic_15 to test_part_02
	- refactor test_null_04 into separate functions and simplifying
	  implementations
	- kill IO verify failure in null/integrity tests by not scanning partition
	- mark each test start and end in dmesg log
	- move all temp files/dir into single directory, and allow user to
	  override default temp dir
  	- derive TID automatically from script name

V2:
	- add `selftests: ublk: move test temp files into a sub directory` for
	  avoiding conflict
	- avoid wq schedule for UBLK_F_NO_AUTO_PART_SCAN(Caleb Sander Mateos)
	- avoid sed in retrieving TID (Alexander Atanasov)
	- commit log typo fix on 2nd patch(Alexander Atanasov)
	- more ublk selftests improvement:
		- rename test_generic_15 to test_part_02
		- refactor test_null_04 into separate functions and simplifying implementations
		- kill IO failure in null/integrity tests by not scanning partition
		


Alexander Atanasov (2):
  selftests: ublk: mark each test start and end time in dmesg

Ming Lei (7):

Add !list_empty(&fcmd->node) check in ublk_batch_cancel_cmd() to ensure
the fcmd hasn't already been removed from the list. Once an fcmd is
removed from the list, it's considered claimed by whoever removed it
and will be freed by that path.

Meantime switch to list_del_init() for deleting it from list.

Add a new feature flag UBLK_F_NO_AUTO_PART_SCAN to allow users to suppress
automatic partition scanning when starting a ublk device.

This is useful for some cases in which user don't want to scan
partitions.

Users still can manually trigger partition scanning later when appropriate
using standard tools (e.g., partprobe, blockdev --rereadpt).

Add automatic TID derivation in test_common.sh based on the script
filename. The TID is extracted by stripping the "test_" prefix and
".sh" suffix from the script name (e.g., test_loop_01.sh -> loop_01).

This removes the need for each test script to manually define TID,
reducing boilerplate and preventing potential mismatches between
the script name and TID. Scripts can still override TID after
sourcing test_common.sh if needed.

Add test_part_01.sh to test the UBLK_F_NO_AUTO_PART_SCAN feature
flag which allows suppressing automatic partition scanning during
device startup while still allowing manual partition probing.

The test verifies:
- Normal behavior: partitions are auto-detected without the flag
- With flag: partitions are not auto-detected during START_DEV
- Manual scan: blockdev --rereadpt works with the flag

Also update kublk tool to support --no_auto_part_scan option and
recognize the feature flag.

This test exercises partition scanning behavior, so move it to
the test_part_* group for consistency.

Encapsulate each test case in its own function that creates the
device, runs checks, and deletes only that device. This avoids
calling _cleanup_test multiple times.

The null target doesn't handle IO, so disable partition scan to avoid IO
failures caused by integrity verification during the kernel's partition
table read.

Log test start and end time in dmesg, so generated log messages
during the test run can be linked to specific test from the test
suite.

Create and use a temporary directory for the files created during
test runs. If TMPDIR environment variable is set use it as a base
for the temporary directory path.
TMPDIR=/mnt/scratch make run_tests
and
TMPDIR=/mnt/scratch ./test_generic_01.sh
will place test directory under /mnt/scratch

I think removing the exports at the end is good - every
test will have to go through _prep_test().
But keeping the longer name - UBLK_TEST_DIR vs
TDIR is better since it can be used inside the tests.
UBLK_TEST_DIR is more descriptive than TDIR.

have fun,
alex
