Subject: [PATCH 01/11] afs: Fix copy_file_range()
Date: Wed, 28 Oct 2020 14:09:55 +0000	[thread overview]
Message-ID: <160389419592.300137.9529932483569358683.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <160389418807.300137.8222864749005731859.stgit@warthog.procyon.org.uk>

The prevention of splice-write without explicit ops made the
copy_file_write() syscall to an afs file (as done by the generic/112
xfstest) fail with EINVAL.

Fix by using iter_file_splice_write() for afs.

Fixes: 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops")
