Latest commit d0c1bc5 Jan 22, 2017 @amir73il ovl: activate new snapshot on freeze_fs
To support "atomic" snapshot take from application persperctive,
keep new configured snapshot pending until the next freeze_fs.

Applications use the following to take a new snapshot:
 mount -o remount,snapshot=<newsnap> /mnt
 fsfreeze -f /mnt
 fsfreeze -u /mnt

New snapshot becomes effective immediately when remounting readonly,
so the following is an alternative the the freeze/thaw API:
 mount -o remount,ro,snapshot=<newsnmap> /mnt
 mount -o remount,rw /mnt

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
