Revert "slub: fix a possible memory leak"

This reverts commit 55652bc65055c44a7f5c0b4af3cc8e678144ea42.
Added Fast Random generator support (frandom) Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
