      ktest: Add BISECT_TRIES to bisect test · 961d9cac
      由 Steven Rostedt (Red Hat) 提交于 
      For those cases that it takes several tries to hit a bug, it would be
useful for ktest.pl to try a test multiple times before it considers
the test as a pass. To accomplish this, BISECT_TRIES ktest config
option has been added. It is default to one, as most of the time a
bisect only needs to try a test once. But the user can now up this
to make ktest run a given test multiple times. The first failure
that is detected will set a bisect bad. It only repeats on success.

Note, as with all race bugs, there's no guarantee that if it succeeds,
it is really a good bisect. But it helps in case the bug is somewhat
reliable.

You can set BISECT_TRIES to zero, and all tests will be considered
good, unless you also set BISECT_MANUAL.

      ktest: Add eval '=~' command to modify variables in config file · c75d22d9
      由 Steven Rostedt (Red Hat) 提交于 
      With the added variable ${KERNEL_VERSION}, it is useful to be
able to use parts of it for other variables.

For example, if you want to create a warnings file for each major
kernel version to test sub versions against you can create
your warnings file with like this:

  WARNINGS_FILE = warnings-file-${KERNEL_VERSION}

But this may add 3.8.12 or something, and we want all 3.8.* to
use the same file, and 3.10.* to use another file, and so on.
With the eval command we can, by adding:

  WARNINGS_FILE =~ s/(-file-\d+\.\d+).*/$1/

Which will chop off the extra characters after the 3.8.

      ktest: Add special variable ${KERNEL_VERSION} · 8e80bf05
      由 Steven Rostedt (Red Hat) 提交于 
      Add a special variable that can be used in other variables called
${KERNEL_VERSION}. This will embed the current kernel version into
the variable. For example:

WARNINGS_FILE = ${OUTPUT_DIR}/warnings-${KERNEL_VERSION}

If the current version is v3.8 then the WARNINGS_FILE will become

  ${OUTPUT_DIR}/warnings-v3.8

      usb: tools: fix a regression issue that gcc can't link to pthread · cb292ce2
      由 Huang Rui 提交于 
      Reproduce:
ray@hr-bak:~/usb$ make -C tools/usb/
make: Entering directory `/home/ray/usb/tools/usb'
gcc -Wall -Wextra -g -lpthread -I../include -o testusb testusb.c
/tmp/cc0EMxfy.o: In function `main':
/home/ray/usb/tools/usb/testusb.c:508: undefined reference to `pthread_create'
/home/ray/usb/tools/usb/testusb.c:531: undefined reference to `pthread_join'
collect2: error: ld returned 1 exit status
make: *** [testusb] Error 1
make: Leaving directory `/home/ray/usb/tools/usb'

Comments:
In the latest version (4.7.3) of gcc compiler, it requres that
libraries must follow the object or source files like below:

"gcc hello.c -lpthread" instead of "gcc -lpthread hello.c"

And it isn't encountered at gcc version 4.7.2.
So this patch fix to move the pthread option after testusb.c.
