including a TV Guide browser/diary), its back to dtrace. Suddenly
decided I was annoyed dtrace wasnt running on the latest kernels
(thanks to everyone who prompted and reminded me of this).
Its a bit of a pain: 2.6.26 and 2.6.37 changed enough things to
make life difficult doing a backwards/forwards series of code changes.
Added to which, my current development laptop is missing some of the
older kernels (available on my other machine), so even if I get
it to compile, I cannot easily guarantee I havent broken a prior
Some things, like the "ioctl()" driver function changed, as Linux
worked out the big-kernel-lock (BKL) - which is a good thing, but
enough to complicate code having to handle old and new kernels.
Others are a bit more curious (e.g. kmalloc() prototype not visible
unless <linux/slab.h> is included).
Also, USDT on my Ubuntu 8.04/32bit is generating bad ELF object
files, which means a clean compile wont proceed to completion.
Then we have more changes to mutexes and the structures, so I need
to be careful we dont break dtrace.
Hope to put out a new release soon that restores "upto dateness".
