Subject: [Qemu-devel] [PULL 1/1] contrib/rdmacm-mux: Fix error condition in hash_tbl_search_fd_by_ifid()
Date: Fri, 18 Dec 2020 21:00:22 +0200 [thread overview]
Message-ID: <20201218190022.31214-2-marcel.apfelbaum@gmail.com> (raw)
In-Reply-To: <20201218190022.31214-1-marcel.apfelbaum@gmail.com>
From: AlexChen <alex.chen@huawei.com>
When fd is not found according to ifid, the _hash_tbl_search_fd_by_ifid()
returns 0 and assigns the result to *fd, so We have to check that *fd is 0,
not that fd is 0.
