Yeah, I know. But it's no problem for me to push this change into the
kernel after some people (including you :-)) have agreed to the principle
of the patch.
I too agree with the principle of the patch. There's no reason to
limit this quantity to 16 bits.
OK, here is the final patch, if nobody objects I'll ask Ben to push the
kernel changes into bitkeeper.
Changes to previous version:
- bumped ipc_perm.seq member to 32 bit
- padded shmid_ds.shm_segsz to prepare for size_t expansion
- added an unrelated LFS change for fcntl.h
Did you test it? There are four combinations to check:
new application/new kernel
old application/new kernel (to test symbol versioning)
new application/old kernel (test translation of old structure to new)
old application/old kernel (this should Just Work if the above cases work)
(but of course you should still check it :-) )
Yeah, I did test all but the new/new combination myself (haven't had time to
recompile xf4 yet), but Jack tested it successfully.
