This looks good, however I'm curious where msecs_to_jiffies originates.
[EMAIL PROTECTED] linux-2.6.6-usb]$ LANG=C grep msecs_to_jiffies include/linux/*.h
include/linux/libata.h:static inline unsigned long msecs_to_jiffies(unsigned long
msecs)
[EMAIL PROTECTED] linux-2.6.6-usb]$
jgarzik's implementation looks good (it addresses an attempt to sleep
for less than a jiffie), but was it moved to a common header yet?
