/*
* This file implements a simple replacement for the buffer manager use
* of the heavyweight hardware lock.
* The lock is a read-write lock. Taking it in read mode is fast, and
* intended for in-kernel use only.
* Taking it in write mode is slow.
*
* The write mode is used only when there is a need to block all
* user-space processes from allocating a
* new memory area.
* Typical use in write mode is X server VT switching, and it's allowed
* to leave kernel space with the write lock held. If a user-space process
* dies while having the write-lock, it will be released during the file
* descriptor release.
*
* The read lock is typically placed at the start of an IOCTL- or
* user-space callable function that may end up allocating a memory area.
* This includes setstatus, super-ioctls and no_pfn; the latter may move
* unmappable regions to mappable. It's a bug to leave kernel space with the
* read lock held.
*
* Both read- and write lock taking may be interruptible for low signal-delivery
* latency. The locking functions will return -EAGAIN if interrupted by a
* signal.
*
* Locking order: The lock should be taken BEFORE any kernel mutexes
* or spinlocks.
