Description Mark Wielaard 2025-10-09 19:46:35 UTC 
fcntl F_GETFD is used to look if a file descriptor number is valid, so --track-fds shouldn't produce an error when a "bad file descriptor" is used with F_GETFD.

    Don't warn about fcntl F_GETFD with --track-fds
    
    fcntl F_GETFD is used to check if a file descriptor is valid, so only
    make sure it isn't a valgrind fd, otherwise we might warn, with
    --track-fds=bad for any bad fd.
