From 0936896056365349afa867c16e9f9100a6707cbf Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Wed, 24 Sep 2014 18:21:04 +0300 Subject: [PATCH] fs: sysfs: return EGBIG on write if offset is larger than file size According to the user expectations common utilities like dd or sh redirection operator > should work correctly over binary files from sysfs. At the moment doing excessive write can not be completed: write(1, "\0\0\0\0\0\0\0\0", 8) = 4 write(1, "\0\0\0\0", 4) = 0 write(1, "\0\0\0\0", 4) = 0 write(1, "\0\0\0\0", 4) = 0 ... Fix the problem by returning EFBIG described in man 2 write. Signed-off-by: Vladimir Zapolskiy Cc: Greg Kroah-Hartman Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
