Subject: [PATCH v2 1/3] libxfs: define BLKREPORTZONEV2 if the kernel does not provide it
Date: Fri, 19 Dec 2025 18:38:08 +0900	[thread overview]
Message-ID: <20251219093810.540437-2-dlemoal@kernel.org> (raw)
In-Reply-To: <20251219093810.540437-1-dlemoal@kernel.org>

Define the BLKREPORTZONEV2 ioctl and the BLK_ZONE_REP_CACHED flag if
the kernel blkzoned.h header file does not provide these, to allow
faster zone reporting in mkfs and repair.
