Subject: [PATCH] virtio_blk: cleanups: remove check obsoleted by CONFIG_LBDAF removal
Date: Fri, 30 Apr 2021 12:36:11 +0200	[thread overview]
Message-ID: <20210430103611.77345-1-sohaib.amhmd@gmail.com> (raw)

From: Sohaib <sohaib.amhmd@gmail.com>

Prior to 72deb455b5ec ("block: remove CONFIG_LBDAF"), it was optional if
the 32-bit kernel support block device and/or file sizes larger than 2 TiB
(considering the sector size is 512 bytes)
But now sector_t and blkcnt_t are always 64-bit in size.
