      aio: Use __kernel_ulong_t to define aio_context_t · ff88943a
      H. Peter Anvin 提交于
      Rather than using "unsigned long" which is ABI-dependent, use
      __kernel_ulong_t to define the externally visible type aio_context_t.
      
      Note: the change in this form will cause unsigned long/unsigned int
      differences on existing ABIs.  If that is unacceptable we may have to
      define a new type.

      signal/timer/event: KAIO eventfd support example · 9c3060be
      Davide Libenzi 提交于
      This is an example about how to add eventfd support to the current KAIO code,
      in order to enable KAIO to post readiness events to a pollable fd (hence
      compatible with POSIX select/poll).  The KAIO code simply signals the eventfd
      fd when events are ready, and this triggers a POLLIN in the fd.  This patch
      uses a reserved for future use member of the struct iocb to pass an eventfd
      file descriptor, that KAIO will use to post events every time a request
      completes.  At that point, an aio_getevents() will return the completed result
      to a struct io_event.  I made a quick test program to verify the patch, and it
      runs fine here:
      
      http://www.xmailserver.org/eventfd-aio-test.c
      
      The test program uses poll(2), but it'd, of course, work with select and epoll
      too.
      
      This can allow to schedule both block I/O and other poll-able devices
      requests, and wait for results using select/poll/epoll.  In a typical
      scenario, an application would submit KAIO request using aio_submit(), and
      will also use epoll_ctl() on the whole other class of devices (that with the
      addition of signals, timers and user events, now it's pretty much complete),
      and then would:
      
      	epoll_wait(...);
      	for_each_event {
      		if (curr_event_is_kaiofd) {
      			aio_getevents();
      			dispatch_aio_events();
      		} else {
      			dispatch_epoll_event();
      		}
      	}

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
