The patch titled
knfsd: fix return value for writes to some files in 'nfsd' filesystem
has been removed from the -mm tree. Its filename was
knfsd-fix-return-value-for-writes-to-some-files-in-nfsd-filesystem.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: knfsd: fix return value for writes to some files in 'nfsd' filesystem
From: NeilBrown <neilb@xxxxxxx>
Most files in the 'nfsd' filesystem are transactional. When you write, a
reply is generated that can be read back only on the same 'file'.
If the reply has zero length, the 'write' will incorrectly return a value of
'0' instead of the length that was written. This causes 'rpc.nfsd' to give an
annoying warning.
This patch fixes the test.
