Subject: [PATCH][next] io_uring: Fix sizeof() mismatch
Date: Mon, 12 Oct 2020 15:03:41 +0100 [thread overview]
Message-ID: <20201012140341.77412-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
An incorrect sizeof() is being used, sizeof(file_data->table) is not
correct, it should be sizeof(*file_data->table).
Addresses-Coverity: ("Sizeof not portable (SIZEOF_MISMATCH)")
Fixes: 5398ae698525 ("io_uring: clean file_data access in files_register")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
