Message-Id: <1514362798-5850-1-git-send-email-fxinrong@gmail.com> Date: Wed, 27 Dec 2017 16:19:58 +0800 From: Sean Fu <fxinrong@...il.com> To: tytso@....edu Cc: adilger.kernel@...ger.ca, linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org, Sean Fu <fxinrong@...il.com> Subject: [PATCH] ext4: Remove repeated test in ext4_file_read_iter. generic_file_read_iter has done the count test. So ext4_file_read_iter don't need to test the count repeatedly.
