Subject: [PATCH] ubifs: Fix reading holes in files
Date: Thu, 4 Feb 2016 12:21:44 +0100 [thread overview]
Message-ID: <1454584904-23740-1-git-send-email-s.hauer@pengutronix.de> (raw)
When a whole block of 4KiB in an ubifs file is zero then the block is
not stored in the filesystem. read_block() returns -ENOENT in this case,
so this return value must be treated as success.
