[PATCH AUTOSEL 6.9 19/40] nvme: fix NVME_NS_DEAC may incorrectly identifying the disk as EXT_LBA.

From: Sasha Levin
Date: Tue Jul 09 2024 - 12:26:30 EST


From: Boyang Yu <yuboyang@xxxxxxxxxxxx>

[ Upstream commit 9570a48847e3acfa1a741cef431c923325ddc637 ]

The value of NVME_NS_DEAC is 3,
which means NVME_NS_METADATA_SUPPORTED | NVME_NS_EXT_LBAS. Provide a
unique value for this feature flag.

Fixes 1b96f862eccc ("nvme: implement the DEAC bit for the Write Zeroes command")
