From 88357580854aab29d27e1a443575caaedd081612 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sun, 12 Apr 2020 21:12:49 -0600 Subject: io_uring: correct O_NONBLOCK check for splice punt The splice file punt check uses file->f_mode to check for O_NONBLOCK, but it should be checking file->f_flags. This leads to punting even for files that have O_NONBLOCK set, which isn't necessary. This equates to checking for FMODE_PATH, which will never be set on the fd in question.
