Not true, you have udelay(), ndelay(), mdelay(), msleep(), ssleep() and the *_interruptible() versions... So you do have functions to delay or sleep in the kernel.
Jesper, AFAICT they both are *not* same. Please CMIIW. Thanks
And if you don't want the kernel to preempt you you can disable preemption while doing your sleeping... not very well behaved kernel code, but you can do it... -- Jesper Juhl <jesper.juhl@xxxxxxxxx> Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
