[PATCH 18/18] nvme: enable logical block size > PAGE_SIZE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Pankaj Raghav <p.raghav@xxxxxxxxxxx>

Don't set the capacity to zero for when logical block size > PAGE_SIZE
as the block device with iomap aops support allocating block cache with
a minimum folio order.
