Subject: [PATCH V2 0/5] block: ignore __blkdev_issue_discard() ret value
Hi,
__blkdev_issue_discard() only returns value 0, that makes post call
error checking code dead. This patch series revmoes this dead code at
all the call sites and adjust the callers.
Please note that it doesn't change the return type of the function from
int to void in this series, it will be done once this series gets merged
smoothly.
For f2fs and xfs I've ran following test which includes discard
they produce same PASS and FAIL output with and without this patch
series [1].
for-next (lblk-fnext) discard-ret (lblk-discard)

For NVMeOF taret I've testing blktest with nvme_trtype=nvme_loop
and all the testcases are passing [2].

[4/6] Formatting TEST_DEV (/dev/nullb0) with XFS...
Formatted /dev/nullb0 with XFS filesystem
Note: SCRATCH_DEV will be formatted by xfstests as needed
[5/6] Creating local.config for xfstests...
Created: /mnt/data100G/xfs-linux/xfstests-dev/local.config
[6/6] Verifying test users...
✓ fsgqa user configured
✓ 123456-fsgqa user configured
✓ fsgqa2 user configured
=== Setup Complete ===
Configuration (null_blk - memory-backed):
TEST_DEV: /dev/nullb0 (20GB, RAM)
TEST_DIR: /mnt/test
SCRATCH_DEV: /dev/nullb1 (20GB, RAM)
SCRATCH_MNT: /mnt/scratch
Config file: /mnt/data100G/xfs-linux/xfstests-dev/local.config
null_blk devices:
nullb0 251:0 0 20G 0 disk
nullb1 251:1 0 20G 0 disk
Device info:
/dev/nullb0: 20.00 GB
/dev/nullb1: 20.00 GB
Advantages of null_blk (memory-backed):
✓ Much faster than loop devices (pure RAM)
✓ No disk I/O overhead
✓ Perfect for kernel testing
You can now run xfstests:
cd /mnt/data100G/xfs-linux/xfstests-dev
./check -g auto # Run all auto tests
./check generic/001 # Run single test
./check -g quick # Run quick test group
To cleanup later, run:
umount /mnt/test /mnt/scratch 2>/dev/null || true
rmmod null_blk

User fsgqa2 already exists
[4/6] Formatting TEST_DEV (/dev/nullb0) with XFS...
Formatted /dev/nullb0 with XFS filesystem
Note: SCRATCH_DEV will be formatted by xfstests as needed
[5/6] Creating local.config for xfstests...
Created: /mnt/data100G/xfs-linux/xfstests-dev/local.config
[6/6] Verifying test users...
✓ fsgqa user configured
✓ 123456-fsgqa user configured
✓ fsgqa2 user configured
=== Setup Complete ===
Configuration (null_blk - memory-backed):
TEST_DEV: /dev/nullb0 (20GB, RAM)
TEST_DIR: /mnt/test
SCRATCH_DEV: /dev/nullb1 (20GB, RAM)
SCRATCH_MNT: /mnt/scratch
Config file: /mnt/data100G/xfs-linux/xfstests-dev/local.config
null_blk devices:
nullb0 251:0 0 20G 0 disk
nullb1 251:1 0 20G 0 disk
Device info:
/dev/nullb0: 20.00 GB
/dev/nullb1: 20.00 GB
Advantages of null_blk (memory-backed):
✓ Much faster than loop devices (pure RAM)
✓ No disk I/O overhead
✓ Perfect for kernel testing
You can now run xfstests:
cd /mnt/data100G/xfs-linux/xfstests-dev
./check -g auto # Run all auto tests
./check generic/001 # Run single test
./check -g quick # Run quick test group
To cleanup later, run:
umount /mnt/test /mnt/scratch 2>/dev/null || true
rmmod null_blk
