=== Add support for memfd_secret file descriptors ===
 +
 +
'''Summary:''' Support C/R of memfd_secret descriptors
 +
 +
There is memfd_secret syscall which allows user to open
 +
special memfd which is backed by special memory range which
 +
is inaccessible by another processes (and the kernel too!).
 +
 +
At the moment CRIU can't dump processes that have memfd_secret's opened.
