-/** @file mmfs.c
- *
- * This file provides the filesystem for memory manager objects used by the
- * DRM.
- *
- * The goal is to have swap-backed object allocation managed through
- * struct file. However, file descriptors as handles to a struct file have
- * two major failings:
- * - Process limits prevent more than 1024 or so being used at a time by
- * default.
- * - Inability to allocate high fds will aggravate the X Server's select()
- * handling, and likely that of many GL client applications as well.
- *
- * This led to a plan of using our own integer IDs (called handles, following
- * DRM terminology) to mimic fds, and implement the fd syscalls we need as
- * ioctls. The objects themselves will still include the struct file so
- * that we can transition to fds if the required kernel infrastructure shows
- * up at a later data, and as our interface with shmfs for memory allocation.
