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 Signed-off-by: Amir Goldstein <firstname.lastname@example.org>

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.
