[PATCH RFC 0/5] perf: Add ioctl to emit sideband events

[Adrian Hunter]

Hi

Here is a stab at adding an ioctl for sideband events.

This is to overcome races when reading the same information
from /proc.

To keep it simple, the ioctl is limited to emitting existing
sideband events (fork, namespaces, comm, mmap) to an already
active context.

There are not yet any perf tools patches at this stage.
