[PATCH v2] Documentation: Document user_events ioctl code

From: Beau Belgrave
Date: Mon Jul 15 2024 - 14:14:36 EST


The user events trace subsystem uses the 0x2A/'*' code for ioctls. These
are published via the uapi/linux/user_events.h header file.

Add a line indicating user events as the owner of the 0x2A/'*' code and
reserve the first 32 sequence numbers.
