In order to be able to analyse the kernel's slab usage, we'd need a list
of allocated objects and their allocation stacks. Kmemleak already
maintains such a list internally, so we expose it via debugfs file.
This file can be post-processed in userspace and converted to a suitable
format for slab
Add a script which converts /sys/kernel/debug/kmemleak_all to the pprof
format, which can be used for analysing memory usage. See
https://github.com/google/pprof.
$ ./kmemleak2pprof.py kmemleak_all

The function tty_port_tty_get() gets a reference to the tty. Since
the code is not using tty_port_tty_set(), the reference is kept
even after closing the tty.
Avoid using tty_port_tty_get() by directly access the tty instance.
