From cf810712cc82cbfab8f08a46ca6c0289d386a303 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 20 Jul 2016 11:31:53 +1000 Subject: [PATCH] xfs: remove s_maxbytes enforcement in xfs_file_read_iter All the three low-level read implementations that we might call already take care of not overflowing the maximum supported bytes, no need to duplicate it here.
