Peter pointed out in this patch https://patchwork.kernel.org/patch/9771921/
that the spinning-lock used at __schedule() should be RCsc to ensure

Currently the VDSO does not handle
clock_gettime( CLOCK_MONOTONIC_RAW, &ts )
on Intel / AMD - it calls
vdso_fallback_gettime()
for this clock, which issues a syscall, having an unacceptably high
latency (minimum measurable time or time between measurements)
of 300-700ns on 2 2.

This header file defines NOVA persistent and volatile superblock
data structures.
It also defines NOVA block layout:
Page 0: Superblock
Page 1: Reserved inodes
Page 2 - 15: Reserved
Page 16 - 31: Inode table pointers
Page 32 - 47: Journal address pointers
Page 48 - 63: Reserved
From: Andiry Xu
NOVA stores offset rather than absolute addresses in pmem.
nova_get_block() and nova_get_addr_off() provide transitions
between these two kinds of addresses.

These routines are incomplete and currently only support reserved inodes,
whose addresses are fixed. This is necessary for fill_super to work.
File/dir operations are left NULL.

NOVA allocates/frees log pages and data pages in the same way.
For block free, NOVA first gets the corresponding free list by
checking the block number, and then inserts the freed range in
the red-black tree. NOVA always merge adjacent free ranges if possible.

Upon a allocation request, NOVA first try the free list on current CPU.
If there are not enough blocks to allocate, NOVA will go to the
free list with the most free blocks.
Caller can specify allocation direction: from low address or from
high address.

NOVA log is a singly linked list of 4KB pmem pages.
Each log page consists of two parts: 4064 bytes for log entries,
and 32 bytes for page tail structure. Page tail contains metadata
about the log page and the address of the next log page in the
linked list.

NOVA uses per-CPU inode map to track inuse inodes.
It works in the same way as the allocator, the only difference is that inode map
tracks in-use inodes, while free list contains free ranges. NOVA always try
to allocate the first available inode number.
