           Summary: epoll_create(0) fails. Mismatch between implementation
                    and manpage
           Product: Documentation
           Version: unspecified
    Kernel Version: 2.6.36
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
        AssignedTo: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
        ReportedBy: kernelbugs-pbvhy9/vjlfAiHgwPnP32rNAH6kLmebB@public.gmane.org
        Regression: No


The epoll_create manpage (current version as of 2010-11-28) contains:

SYNOPSIS
...
    int epoll_create(int size);
...
DESCRIPTION
...
    (Nowadays, size is ignored; see NOTES below.)
...
ERRORS
    EINVAL size is not positive.
...
NOTES
    Since Linux 2.6.8, the size argument is unused. ...


on the other hand, fs/eventpoll.c contains:
SYSCALL_DEFINE1(epoll_create, int, size)
{
        if (size <= 0)
                return -EINVAL;

        return sys_epoll_create1(0);
}

The size parameter is not ignored as stated in the manpage.
Please correct the manpage or remove the check inside the implementation.
