Subject: [PATCH 15/15] xfs: support returning partial reflink results
Date: Thu, 04 Oct 2018 17:46:27 -0700	[thread overview]
Message-ID: <153870038708.29072.12551299927251008289.stgit@magnolia> (raw)
In-Reply-To: <153870027422.29072.7433543674436957232.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Back when the XFS reflink code only supported clone_file_range, we were
only able to return zero or negative error codes to userspace.  However,
now that copy_file_range (which returns bytes copied) can use XFS'
clone_file_range, we have the opportunity to return partial results.
For example, if userspace sends a 1GB clone request and we run out of
space halfway through, we at least can tell userspace that we completed
512M of that request like a regular write.
