Hide/Block files in any filesystem:

Introduction:
Its an modified wrapfs(Stackable filesystem) to hide/block any files or
directories in any filesystem. It keeps the information of the hidden/blocked
files in-memory so after remount it is lost.

It is compiled and tested on linux kernel version 4.4.x

Installation:

WRAPFS:
1> cd wrapfs/
2> make
3> insmod wrapfs.ko

TOOL:
1> cd tool/
2> make wrapfsctl

Configuration:

mount wrapfs on any filesystem you want to use underneath.
eg:
	mount -t ext4 /dev/sda /mnt
	mount -t wrapfs /mnt /mnt

# wrapfsctl [options]
		hide     <path>
		unhide   <path>
		block    <path>
		unblock  <path> <inode_number> <mntpt>
		list     <mntpt>
