Subject: Re: [PATCH] tracing: remove unreachable trace_array_put
Date: Mon, 15 Jul 2024 16:47:36 +0300	[thread overview]
Message-ID: <98c01cc6-dcee-46d0-bdc8-0e35165ec68b@ancud.ru> (raw)

As nonseekable_open() documentation states:
"The function is not supposed to ever fail, the only
reason it returns an 'int' and not 'void' is so that it can be plugged
directly into file_operations structure."

So it seems, that it will not fail anytime as it is not meant to? Otherwise,
there will be a huge problem with leaks in many other parts of code, as
there are plenty of places, where nonseekable_open() is not checked after
resource allocations.
