Merge tag 'ata-6.19-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux
Pull ata fix from Niklas Cassel:
- The DELLBOSS VD SATA controller times out when sending I/Os of size
4096 KiB or larger, even though it claims LBA48 support, which per
the ACS standard requires support for a maximum command size of
65535 sectors, i.e. 32 MiB - 512. Thus, quirk the device so that it
sets a lower maximum command size (me)
* tag 'ata-6.19-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux:
ata: libata-core: Quirk DELLBOSS VD max_sectors
ata: libata: Move quirk flags to their own enum
