Michael Kerrisk 19416046c5 mount_namespaces.7: Tweak discussion of "less privileged" mount namespace 
Eric Biederman:

    I hate to nitpick, but I am going to say that when I read
    the text above the phrase "mount namespace of the process
    that created the new mount namespace" feels wrong.

    Either you use unshare(2) and the mount namespace of the
    process that created the mount namespace changes.

    Or you use clone(2) and you could argue it is the new child
    that created the mount namespace.

    Having a different mount namespace at the end of the
    creation operation feels like it makes your phrase confusing
    about what the starting mount namespace is.  I hate to use
    references that are ambiguous when things are changing.

Michael Kerrisk a0c9733194 mount_namespaces.7: Clarify description of "less privileged" mount namespaces 
The current text talks about "parent mount namespaces", but there
is no such concept. As confirmed by Eric Biederman, what is mean
here is "the mount namespace this mount namespace started as a
copy of". So, this change writes up Eric's description in a more
detailed way.

Carlos O'Donell dbb01cbbdb pthread_setcancelstate.3, pthreads.7, signal-safety.7: Describe issues with cancellation points in signal handlers 
In a recent conversation with Mathieu Desnoyers I was reminded
that we haven't written up anything about how deferred
cancellation and asynchronous signal handlers interact. Mathieu
ran into some of this behaviour and I promised to improve the
documentation in this area to point out the potential pitfall.

Thoughts?

8< --- 8< --- 8<
In pthread_setcancelstate.3, pthreads.7, and signal-safety.7 we
describe that if you have an asynchronous signal nesting over a
deferred cancellation region that any cancellation point in the
signal handler may trigger a cancellation that will behave
as-if it was an asynchronous cancellation. This asynchronous
cancellation may have unexpected effects on the consistency of
the application. Therefore care should be taken with asynchronous
signals and deferred cancellation.
