Subject: [PATCH v2 1/2] xfs: fix incorrect argument count check
Date: Tue, 25 Apr 2017 14:51:05 -0600	[thread overview]
Message-ID: <20170425205106.20576-1-ross.zwisler@linux.intel.com> (raw)

t_mmap_dio.c actually requires 4 arguments, not 3 as the current check
enforces:

	# ./src/t_mmap_dio
	usage: t_mmap_dio <src file> <dest file> <size> <msg>
	# ./src/t_mmap_dio  one two three
	open src(No such file or directory) len 0 (null)

Signed-off-by: Ross Zwisler <ross.zwisler@linux.intel.com>
Fixes: 456581661b4d ("xfs: test per-inode DAX flag by IO")
