Subject: [RFC PATCH 01/12] btrfs-progs: build: Check zoned block device support
Date: Fri, 10 Aug 2018 03:10:54 +0900 [thread overview]
Message-ID: <20180809181105.12856-1-naota@elisp.net> (raw)
In-Reply-To: <20180809180450.5091-1-naota@elisp.net>
If the kernel supports zoned block devices, the file
/usr/include/linux/blkzoned.h will be present. Check this and define
BTRFS_ZONED if the file is present.
If it present, enables HMZONED feature, if not disable it.
