For my diploma i'am modifying the Linux Kernel to support ACL's. At some places the Kernel has to sleep on interal structures and after wake up the process has to run as soon as possible to minimize delay (e.g. the acl-header-cache). As i know the traditional approach (Maurice J. Bach: The Design of the UNIX Operating System) is to set the process to a fixed (and high) "sleep priority" on which the process will run after wake up.

But i couldn't find the related code in the Linux kernel (2.0.33).

Does anybody know how Linux doing this??

thanks for every help
