Subject: [PATCH 02/17] common: Always return enum filetype in file_name_detect_type_offset()
Date: Wed,  6 Mar 2019 23:49:11 -0800	[thread overview]
Message-ID: <20190307074926.20539-3-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190307074926.20539-1-andrew.smirnov@gmail.com>

None of the callers of file_name_detect_type_offset() are prepared to
deal with negative error code. Change the code to return
filetype_unknown if open_and_lseek() fails.
