13) Log Message: The problem was the position of the parenthesis, which made "fd" receive the result of the < (lower than) operation, instead of the actual return value from open. This implicates a lot of trouble in any subsequent reference to fd, used in write and mmap. Because of this, mmap was returning an error number (ENODEV), instead of a valid memory address, which created the mprotect trouble. Fix by Jose Otavio Rizzatti Ferreira <joseferr@br.ibm.com>

14) Log Message: Patrick Kirsch <pkirsch@suse.de> personally thinks, it would be better to print out the "actual" return code from sysconf call instead of the errno, which may lead to confusion, because the actual return code from the failing sysconf is probably not 0 (as errno is defined in previous context).

Since msgmni now scales to the memory size, it may reach big values.
To avoid forking 2*msgmni processes and create msgmni msg queues, do not take
msgmni from procfs anymore.
Just define it as 16 (which is the MSGMNI constant value in linux/msg.h)

Also fixed the Makefiles in ipc/lib and ipc/msgctl: there was no dependency
on the lib/ipc*.h header files.

26) Log Message:
Here is a second round of cleanup and fixes for the realtime testcases.

1) Make sched_jitter use the create_fifo_thread() library function instead of an open coded solution,
2) Prio-wake calls rt_init() twice, remove the second call,
3) Make sbrk_mutex less verbose by default. One can still use the -v option to get the whole output,
4) It's better to calculate the histogram before saving it. This was introduced in an earlier commit of mine fixing the quantile calculation, 5) Fix runtime displaying of the min and max latencies (when used with -v3). While at it, remove an uneeded avg variable,
6) Various tests still have a hardcoded value for the quantile nines. Use a value automatically calculated from the number of iterations,
7) The log10() call used for automatic quantile nines calculation returns a double result. Cast it to an int. The exp10() call used in stats_quantiles_calc() for checking purposes returns a double result which is compared against a long. Cast it to a long. This allows the following comparison: data->size < (long)exp10(quantiles->nines) to really be false when quantiles->nines has been calculated as log10(data->size).
More generally, it seems that (at least with gcc 4.1.1):
long i = 10000;
double f = exp10(log10(i))

yields (i < f) being true due to rounding,
8) Add latency tracing capability to pthread_kill_latency as is already done on a few other latency tests (gtod_latency, sched_latency, ...),
9) The '::' optional argument specifier for getopt used by the '-v' option is a GNU extension, is not portable and does not work. For example it's not even described in the Debian getopt(3) manpage. Make the '-v' option require a non optional argument,
10)The print buffer is only ever flushed when it is full. Add flushing when the test terminates vi atexit(),
11)The 'period missed' check of the thread first loop should not depend on the thread starting time. This is especially visible on 'slow' platforms where one cannot run the test if thread creation takes a long time. Fix it by removing this dependency. All delays are now calculated relative to when the thread starts,

waitpid tests: Fix failure detection flag initialization.
On a similar pattern as waitpid06 and waitpid07, waitpid08-13 use a failure detection flag (called 'fail' instead of 'flag'). However except in waitpid09, this flag may be used uninitialized, which causes the test to randomly report failure. This patch ensures that the flag is reset at the beginning of each loop.

43) Log Message:
CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID are also supported besides CLOCK_REALTIME and CLOCK_MONOTONIC. That's the cause of the failure of clock_gettime03, timer_create02 and timer_create04. Another cause is that struct sigevent evp is assigned with invalid values when option is 1. That's the cause of the failure of timer_create02 and timer_create03. CLOCK_REALTIME_HR and CLOCK_MONOTONIC_HR have been removed in the later kernel versions, hence the failures in the test. I am still trying to find out if any kernel versions used to support these. CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID are supported from 2.6.12 kernel version onwards and the test case needs to be modified for this change. Also in timer_create02.c, setup_test() case1 needs to be modified so as to make evp NULL instead of its members. Since the testcase behaves differently for different kernel versions, a version check needs to be added for making it pass across versions. I'm removing the HR clocks from the tests along with other changes, by, Anoop V. Chakkalakkal <anoop.vijayan@in.ibm.com>

- Fix return value check from shmat. In case of error, this wrong check was leading to a seg-fault.
LTP-kill05-shmid_delete-fix.patch:
- Fix deletion of the memory segment. Due to the change of process UID during the test, the segment was created by ROOT and deleted (or tried to be deleted) by user "bin". This is of course not possible. And it is also impossible to switch back uid to ROOT. Solution adopted : doing a fork in which the test is performed. The initial process staying with ROOT uid.
LTP-kill05-concurrency-fix.patch
- Paranoia concurrency fix. I have not encounter any real issue, but it is probably safer to be sure each process is using a different segment. -> use tst_tmpdir, to make getipckey generating a different key for each running process, by, Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>

48) Log Message:
1) The pi-tests don't use the librttest infrastructure and simply duplicate code. This patch ensures that those tests use librttest.
2) The thread-clock test doesn't use the librttest infrastructure. This patch ensures that it does.
3) Adds missing headers to the following files,

49) Log Message: Fixes a concurrency issue in shmat02. The second IPC key used in this test was generated doing a ++ on the first key. By doing this, it makes possible to get a conflict with a key generated by another process. To fix this, I just do a new call to getipckey() and check if the key is different from the previously generated one,

This patch fixes the testcases mismerge due to the patch "There are numerous cleanups, fixes and features went into our ..." from Sudhanshu Singh. Turned out there was less damage than I thought. Hopefully, it should restore the fixes and cleanups which were reverted before the February Release.
