Subject: [PATCH] io_uring: Fix uninitialized use of ret in io_eventfd_register()
Date: Wed, 9 Feb 2022 18:26:37 +0800 [thread overview]
Message-ID: <[email protected]> (raw)
In some scenarios, ret is not assigned in the whole process, so it
needs to be initialized at the beginning.
Clean up the following clang warning:
fs/io_uring.c:9373:13: note: initialize the variable 'ret' to silence
this warning.
