Changes to individual pages
---------------------------

clone.2
    Michael Kerrisk
        Note that CLONE_THREAD causes similar behavior to CLONE_PARENT
            The introductory paragraphs note that "the calling process" is
            normally synonymous with the "the parent process", except in the
            case of CLONE_PARENT. The same is also true of CLONE_THREAD.
    Christian Brauner  [Michael Kerrisk]
        Mention that CLONE_PARENT is off-limits for inits

listen.2
    Michael Kerrisk  [Peter Gajdos]
        The 'somaxconn' default value has increased to 4096

open.2
    Adam Borowski
        No need for /proc to make an O_TMPFILE file permanent
            In the example snippet, we already have the fd, thus there's no
            need to refer to the file by name.  And, /proc/ might be not
            mounted or not accessible.
    Michael Kerrisk  [Joseph C. Sible]
        In O_TMPFILE example, describe alternative linkat() call
            This was already shown in an earlier version of the page,
            but Adam Borowski's patch replaced it with an alternative.
            Probably, it is better to show both possibilities.

ptrace.2
    Denys Vlasenko
        PTRACE_EVENT_STOP does not always report SIGTRAP

stime.2
    Michael Kerrisk
        Note that stime() is deprecated

sysctl.2
    Michael Kerrisk
        This system call was removed in Linux 5.5; adjust the page accordingly

cmsg.3
    Rich Felker
        Clarify alignment issues and correct method of accessing CMSG_DATA()
console_codes.4
    Adam Borowski
        Document \e[90m to 97, 100 to 107
    Adam Borowski
        \e[21m is now underline
    Adam Borowski
        Update \e[38m and \e[48m

cgroups.7
    Michael Kerrisk
        The v2 freezer controller was added in Linux 5.2
    Michael Kerrisk
        Split discussion of cgroups.events file and v2 release notification
            In preparation for adding a description of the "frozen" key.
    Michael Kerrisk
        Describe the cgroup.events "frozen" key
    Michael Kerrisk
        Improve the discussion of the advantages of v2 release notification

unix.7
    Michael Kerrisk
        The PID sent with SCM_CREDENTIALS must match an existing process

ldconfig.8
    DJ Delorie
        Document file filter and symlink pattern expectations
