[PATCH v2 0/8] ata: libata: Quirk DELLBOSS VD max_sectors

[Niklas Cassel <cassel@kernel.org>]

Hello there,

a recent change:
commit 9b8b84879d4a ("block: Increase BLK_DEF_MAX_SECTORS_CAP")

bumped the default max_sectors_kb from 1280 to 4096.

It seems like a lot for SATA controllers are buggy and don't really like
this, see:
https://bugzilla.kernel.org/show_bug.cgi?id=220693

For now, we only add a DELLBOSS VD max_sectors quirk, but surely we will
need to quirk additional controllers.


Changes since v1:
-Introduced a generic quirk (ATA_QUIRK_MAX_SEC) that also has a value.
-Added libata.force parameter max_sec=<sectors>.
-Use the correct model string for DELLBOSS VD.
