[PATCH] ata: Disable NCQ_TRIM on Micron 1100 drives

[Pawel Zmarzly]

Micron 1100 drives lock up when encountering queued TRIM command.
It is a quite old hardware series, for past years we have been
running our machines with these drives using
libata.force=noncqtrim.

Please align ATA_HORKAGE_ZERO_AFTER_TRIM to ATA_HORKAGE_NO_NCQ_TRIM,
instead of aligning it to NULL. (That way it matches the existing entries.)

I think you forgot your Signed-off-by tag this time.

See:
https://docs.kernel.org/process/submitting-patches.html#the-canonical-patch-format

E.g.

<commit message>
...
Signed-off-by: Author <author@mail>
---
V2 -> V3: Removed redundant helper function
V1 -> V2: Cleaned up coding style and addressed review comments

path/to/file | 5+++--
...


If you run ./scripts/checkpatch.pl against your patch,
it should tell you if the Signed-off-by tag is missing.


Kind regards,
Niklas

This does not apply cleanly on the fo-6.6 branch. Can you rebase your patch
please and make sure it applies to libata tree for-6.6 branch ?

Don't bother. I applied the patch manually with some minor tweaks.
It is now queued for 6.6. Thanks.
