Subject: [PATCH 4.14 13/22] xfs: map unwritten blocks in XFS_IOC_{ALLOC,FREE}SP just like fallocate
Date: Mon, 10 Jan 2022 08:23:06 +0100 [thread overview]
Message-ID: <20220110071814.707995874@linuxfoundation.org> (raw)
In-Reply-To: <20220110071814.261471354@linuxfoundation.org>
From: Darrick J. Wong <djwong@kernel.org>
commit 983d8e60f50806f90534cc5373d0ce867e5aaf79 upstream.
The old ALLOCSP/FREESP ioctls in XFS can be used to preallocate space at
the end of files, just like fallocate and RESVSP. Make the behavior
consistent with the other ioctls.
