This is because we use file->f_op to detect whether a # pidfd is passed and O_PATH fds have their file->f_op set to empty_fops # in do_dentry_open() and thus fail the test. # # Thus, there is no regression. It's just semantically correct to use # fdget() and return an error right from there instead of taking a # reference and returning an error later. # # Signed-off-by: Christian Brauner <christian@brauner.io> # Acked-by: Oleg Nesterov <oleg@redhat.com> # Cc: Arnd Bergmann <arnd@arndb.de> # Cc: "Eric W.
