. A bunch of anticipatory scheduler patches.
For the first time ever, AS is working well with both IDE and SCSI
under all the usual tests.
It works just fine on SCSI with zero TCQ tags, and with four TCQ tags.
At eight tags, read-vs-write performace is starting to measurably drop off.
At 32 tags it is about 2000x slower than at zero or four tags.
My recommendation, as always, is to disable SCSI TCQ completely. If you
really must, set it to four tags.
. Now using 64-bit dev_t with a 32:32 split. There's a new `mknod64()'
syscall for creating these device nodes, and support for this in ext2 and
ext3. There is no corresponding userspace mknod(1) as far as I know.
. There is a fancy memory debugging patch from Manfred here. On ia32 it
will unmap pages from kernel virtual address space when they are freed. It
will also unmap slab objects which are >= 4 kilobytes in size. This is to
force an oops if anyone touches freed-up memory.
This might be buggy on SMP, due to missing TLB invalidations (put them
in, and they will deadlock). Or it might not be buggy, due to the
behaviour of the special vmalloc pagefault handler.
Anyway, it's cool, and should work OK on uniprocessor at least.
. Lots of new random fixes. This is a 13 megabyte diff...
