Simply because the latter is the only one to have been moved to the kernel. That happened because the trigger for bdflush is an internal kernel wait queue, whereas the trigger for update is a timer. Timers can be easily done in user space. > I believe it is not that hard to code bdflush in the kernel, where we > lose nothing, but save few pages of memory.

It will save memory; it will also, more importantly, save non-pageable memory (although the kernel thread will still need its own kernel stack, it will not need the extra page tables which accompany a user-space process). --Stephen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.altern.org/andrebalsa/doc/lkml-faq.html | ||||||||||||
