[uml-user] [info] syscalls mmap and mremap no longer fails w/ SLUB

[Toralf F. <tor...@gm...>]

Since today both syscalls seems to work fine with SLUB and guest kernel
linux-v3.9-10998-g1b9b170 at a stable Getnoo 32 bit, now just these 4
are still forcing kernel bugs if stressed with trinity :

-x mount -x request_key -x add_key -x keyctl

(me just re-tested both b/c I saw a lot af SLAB/SLUB related merges into
mainline but ofc I'm unsure when those 2 were fixed).

Good to hear. MM folks fixed a off-by-one error a few days ago.
Maybe you ran into that problem...
