The \"clockid\"\nparameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.\n\nThe timerfd_settime() API give new settings by the timerfd fd, by optionally\nretrieving the previous expiration time (in case the \"otmr\" parameter is not\nNULL).\n\nThe time value specified in \"utmr\" is absolute, if the TFD_TIMER_ABSTIME bit\nis set in the \"flags\" parameter.  Otherwise it\u0027s a relative time.\n\nThe timerfd_gettime() API returns the next expiration time of the timer, or\n{0, 0} if the timerfd has not been set yet.\n\nLike the previous timerfd API implementation, read(2) and poll(2) are\nsupported (with the same interface).

      "message": "make timerfd return a u64 and fix the __put_user\n\nDavi fixed a missing cast in the __put_user(), that was making timerfd\nreturn a single byte instead of the full value.\n\nTalking with Michael about the timerfd man page, we think it\u0027d be better to\nuse a u64 for the returned value, to align it with the eventfd\nimplementation.\n\nThis is an ABI change.  The timerfd code is new in 2.6.22 and if we merge this\ninto 2.6.23 then we should also merge it into 2.6.22.x.  That will leave a few\nearly 2.6.22 kernels out in the wild which might misbehave when a future\ntimerfd-enabled glibc is run on them.\n\nmtk says: The difference would be that read() will only return 4 bytes, while\nthe application will expect 8.  If the application is checking the size of\nreturned value, as it should, then it will be able to detect the problem (it\ncould even be sophisticated enough to know that if this is a 4-byte return,\nthen it is running on an old 2.6.22 kernel).  If the application is not\nchecking the return from read(), then its 8-byte buffer will not be filled --\nthe contents of the last 4 bytes will be undefined, so the u64 value as a\nwhole will be junk.\n\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Davi Arnaut \u003cdavi@haxent.com.br\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "signal/timer/event: timerfd core\n\nThis patch introduces a new system call for timers events delivered though\nfile descriptors.  This allows timer event to be used with standard POSIX\npoll(2), select(2) and read(2).  As a consequence of supporting the Linux\nf_op-\u003epoll subsystem, they can be used with epoll(2) too.\n\nThe system call is defined as:\n\nint timerfd(int ufd, int clockid, int flags, const struct itimerspec *utmr);\n\nThe \"ufd\" parameter allows for re-use (re-programming) of an existing timerfd\nw/out going through the close/open cycle (same as signalfd).  If \"ufd\" is -1,\ns new file descriptor will be created, otherwise the existing \"ufd\" will be\nre-programmed.\n\nThe \"clockid\" parameter is either CLOCK_MONOTONIC or CLOCK_REALTIME.  The time\nspecified in the \"utmr-\u003eit_value\" parameter is the expiry time for the timer.\n\nIf the TFD_TIMER_ABSTIME flag is set in \"flags\", this is an absolute time,\notherwise it\u0027s a relative time.\n\nIf the time specified in the \"utmr-\u003eit_interval\" is not zero (.tv_sec \u003d\u003d 0,\ntv_nsec \u003d\u003d 0), this is the period at which the following ticks should be\ngenerated.\n\nThe \"utmr-\u003eit_interval\" should be set to zero if only one tick is requested.\nSetting the \"utmr-\u003eit_value\" to zero will disable the timer, or will create a\ntimerfd without the timer enabled.\n\nThe function returns the new (or same, in case \"ufd\" is a valid timerfd\ndescriptor) file, or -1 in case of error.\n\nAs stated before, the timerfd file descriptor supports poll(2), select(2) and\nepoll(2).  When a timer event happened on the timerfd, a POLLIN mask will be\nreturned.\n\nThe read(2) call can be used, and it will return a u32 variable holding the\nnumber of \"ticks\" that happened on the interface since the last call to\nread(2).  The read(2) call supportes the O_NONBLOCK flag too, and EAGAIN will\nbe returned if no ticks happened.\n\nA quick test program, shows timerfd working correctly on my amd64 box:\n\nhttp://www.xmailserver.org/timerfd-test.c\n\n[akpm@linux-foundation.org: add sys_timerfd to sys_ni.c]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
