I noticed this announcement of kernel 2.6.37-rc1
http://lkml.org/lkml/2010/11/1/82 , and in particular that the BKL is
largely gone. To my (fairly uninformed) mind, it sounds as though
taking the lock out of the kernel should make the kernel more
responsive and maybe make the RT or low-latency kernel easier to do,
or even unnecessary maybe ? I'd be interested to hear the comments on
this from our experts.
