      timerfd: new timerfd API · 4d672e7a
      Davide Libenzi authored
      This is the new timerfd API as it is implemented by the following patch:
      
      int timerfd_create(int clockid, int flags);
      int timerfd_settime(int ufd, int flags,
      		    const struct itimerspec *utmr,
      		    struct itimerspec *otmr);
      int timerfd_gettime(int ufd, struct itimerspec *otmr);
      
      The timerfd_create() API creates an un-programmed timerfd fd.  The "clockid"
      parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.
      
      The timerfd_settime() API give new settings by the timerfd fd, by optionally
      retrieving the previous expiration time (in case the "otmr" parameter is not
      NULL).
      
      The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit
      is set in the "flags" parameter.  Otherwise it's a relative time.
      
      The timerfd_gettime() API returns the next expiration time of the timer, or
      {0, 0} if the timerfd has not been set yet.
      
      Like the previous timerfd API implementation, read(2) and poll(2) are
      supported (with the same interface).  Here's a simple test program I used to
      exercise the new timerfd APIs:

      [PATCH] Add epoll compat_ code to fs/compat.c · f6dfb4fd
      Davide Libenzi authored
      IA64 and ARM-OABI are currently using their own version of epoll compat_
      code.
      
      An architecture needs epoll_event translation if alignof(u64) in 32 bit
      mode is different from alignof(u64) in 64 bit mode.  If an architecture
      needs epoll_event translation, it must define struct compat_epoll_event in
      asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use
      compat_sys_epoll_ctl and compat_sys_epoll_wait.
      
      All 64 bit architecture should use compat_sys_epoll_pwait.
      
      [sfr: restructure and move to fs/compat.c, remove MIPS version
      of compat_sys_epoll_pwait, use __put_user_unaligned]

      [PATCH] select: fix returned timeval · 643a6545
      Andrew Morton authored
      With David Woodhouse <dwmw2@infradead.org>
      
      select() presently has a habit of increasing the value of the user's
      `timeout' argument on return.
      
      We were writing back a timeout larger than the original.  We _deliberately_
      round up, since we know we must wait at _least_ as long as the caller asks
      us to.
      
      The patch adds a couple of helper functions for magnitude comparison of
      timespecs and of timevals, and uses them to prevent the various poll and
      select functions from returning a timeout which is larger than the one which
      was passed in.
      
      The patch also fixes a bug in compat_sys_pselect7(): it was adding the new
      timeout value to the old one and was returning that.  It should just return
      the new timeout value.
      
      (We have various handy timespec/timeval-to-from-nsec conversion functions in
      time.h.  But this code open-codes it all).

      [PATCH] compat: be more consistent about [ug]id_t · 202e5979
      Stephen Rothwell authored
      When I first wrote the compat layer patches, I was somewhat cavalier about
      the definition of compat_uid_t and compat_gid_t (or maybe I just
      misunderstood :-)).  This patch makes the compat types much more consistent
      with the types we are being compatible with and hopefully will fix a few
      bugs along the way.
      
      	compat type		type in compat arch
      	__compat_[ug]id_t	__kernel_[ug]id_t
      	__compat_[ug]id32_t	__kernel_[ug]id32_t
      	compat_[ug]id_t		[ug]id_t
      
      The difference is that compat_uid_t is always 32 bits (for the archs we
      care about) but __compat_uid_t may be 16 bits on some.

      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!
