[PATCH v4 0/6] ata: libata: Improve max sectors quirk handling

[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

Therefore, improve the max sectors quirk handling, to only have one max
sectors quirk, which also takes an additional value.

This reduces the number of ATA_QUIRK_MAX_SEC_XXX quirks from 3 to 1,
while also making it easier to quirk additional devices with different
max sector limits.


The series is based on libata for-next branch, and the intention is to
queue this series up for v7.0.


Changes since v3:
-Pick up tags from Damien.
-Fix minor review comments from Damien.
