It's hard to have too many inter-module dependencies when most of the core modules no longer even take the kernel lock any more. In the VFS layer, we still have - the ioctl thing, obviously. That's just mind-numbing "move things down", not hard per se. But there's a *lot* of them (and I suspect the huge majority of them don't actually need it, since they'd already be racing against read/write anyway if they did). - default_llseek(). Probably the same, just a lot less of it. - superblock read/write. and the latter one in particular is really dubious (we already have "[un]lock_super()" around it all, I think). The core kernel, VM and networking already don't really do BKL. And it's seldom the case that subsystems interact with other unrelated subsystems outside of the core areas. So it's a lot of work, no doubt, but I do think we should be able to do it. The most mind-numbing part is literally all the ioctl crud. There's more ioctl points than there are lock_kernel() calls left anywhere else. Linus --
